I love Fate. I am using it to run what I'm calling my "sedition sandbox" campaign (there's an evil empire, you've been sent to its capital as spies and saboteurs, now tell me how you bring it down from the inside).
It's been working great. On our best nights, we hit a tone reminiscent of Andor as my players hit key targets, turn their enemies against each other, and grapple with just how far they are willing to go in the name of the cause.
Check out Kingdom! It's a less traditional game, but it strips away just about everything except for the power, politics, and intrigue, and does it rather well, in my mind. It can handle scopes as broad as a galaxy spanning empire or as narrow as an after school fan club.
Do note that it focuses primarily on internal politics, in that all the players are expected to be members of the same organisation and want it to succeed. But they should have very different ideas about how to accomplish that or what success looks like, which drives the ebbs and flows of power
Yeah, it works well enough. I haven't had any issues, at least. On Linux, I prefer something along the lines of Workspace Matrix to get a proper two dimensional layout, but on Windows, the built-in workspaces have been at least sufficient for game night and don't require any additional setup
I use LogSeq to organise all my notes. My group meets in-person, but I use Foundry to put background art, NPC portraits, etc. up on a screen, as well as to manage any NPC character sheets.
It may stretch the definition of 'tool' a bit, but the other thing I do is set up my laptop with four desktops/workspaces (notes, Foundry, music, rules) so I can switch between them with Ctrl+Windows+Left/Right. It's a minor thing, but I am constantly surprised by how many people I run into who don't know that you can do it. Switching desktops feels like much less friction to me than Alt+Tabbing between windows for some reason.
Outer Wilds. Endings of both the main game and the DLC can still get me to tear up a bit. I saw a post somewhere, don't remember, that said something along the lines of "Listening to the Outer Wilds OST is the only way I feel my feelings any more." It's about like that.
Seconding Fate, the rules do a good job of supporting the fiction rather than encumbering it. I felt it very much supported that feeling of "I can do anything I can reasonably imagine."
To help with the tyranny of the blank page, I'd recommend coming up with a pregenerated character to demo how it all works. Then, encourage her to change or adjust anything she wants to on the sheet. My players initially found it easier to modify something to their liking than to come up with something from scratch.
Magic can be as simple as "Roll your Lore skill" if you want or you can look up several more detailed add-ons that are out there, like Fate High Fantasy magic.

I have put hundreds of hours into RoR2 on PC, love the game. I recently purchased a Switch copy so I could play with a friend of mine who is console-only. Sadly, the port is still in a pretty bad place when I checked last (2-3 weeks ago).
I am not expecting the PC and console experience to be identical by any stretch, but I am talking about basic issues like the music on each stage cutting out after playing for only 10-15 seconds, wonky damage (Beetle Queens absolutely massacring us even on Rainstorm if we touched their projectile splash zones), and all the other miscellaneous issues from the patch like logbook being glitches, unlocks being unpredictable, etc.
I think it could potentially be fixed, but I would give them time to put out a few more bugfix patches before I considered a console purchase
I have not yet played Return of the Obra Dinn, but it is always high up on the list when I look for games like Outer Wilds. I'm a huge fan of Outer Wilds, so maybe the recommendation can work in reverse
From what I have heard, the deduction is not as intense as in Obra Dinn, but there is very little hand holding, and the whole game has been brilliantly designed so that it is driven entirely by your natural human curiosity. Once you get through the initial "tutorial" section (probably the roughest part of the game, push through!) the whole game is wide open. See something weird orbiting a distant planet? You can go straight there and start poking around. If you follow the leads that turn up there, you will eventually even figure out what it is, and why it is there. Do that enough and you'll eventually figure out the strange mystery of your home solar system.
Can't recommend it highly enough, but you only get to play it without knowing the secrets once, so go in as blind as you can. It took me 20-30 hours to "solve" the main game, maybe another 20 for the DLC, which is also well worth it
Maybe FATE would be worth checking out?
Things I think it might hit for you:
Characters are good at what they're good at. You define the core concepts of your character and use them to get bonuses. Your character is a Highly Trained Ninja? Then yeah, you'll be getting bonuses to all your sneaking, hiding, acrobatics, flashy martial arts, etc. Plus, the way the maths work, the dice have a bell curve centred at +0 (extremes of +4/-4) so the +4 in your character's best skill is constantly having a huge impact on outcomes. Contrast that with your +7 in D&D which is still missing 25% of the time
Fairly simple rules. The core is, describe what you're trying to do, and then use one of four basic actions to model it if a roll seems appropriate: Attack, Defend, Overcome (beat a DC) or Create an Advantage (alter circumstances/environment/characters to tip the odds in your favour). However, there's a little more for combat and also a meta currency to manage, which I'll talk about below
Very quick to get off the ground. Character creation can take only minutes if you want. No mucking about with long lists of feats and spells and class builds and whatnot. You're actively encouraged to leave spots blank and fill them in during play when an idea strikes you, great for new and unsure players
Completely setting agnostic, it's flexible enough to do almost anything
Things I think it might miss for you:
FATE's approach is much closer to a story game, especially compared to something like D&D which leans towards the simulation side of the spectrum. Its meta currency, Fate points, aims to emulate the feel of an action movie or TV show. Spend points to do awesome things, get them back for accepting challenges, complications, and setbacks in your character's arc. That latter point especially often means the table needs to have a "writer's room" mentality, which isn't a good fit for all players.
FATE doesn't really try to do certain things that D&D does, like strict resource management, accumulation of powerful loot, big powerful character level ups, or dungeon crawling. It can be done, and guides are out there to help you do so, but you will be bolting a lot of extras onto the system, so watch out if those are what you enjoy
Which brings me to the last point, FATE is a system that really wants you to hack it and make it your own. It's very resilient to this sort of thing compared to something like D&D where getting some maths wrong can make things unfun in innumerable ways, but it does take effort and thought regardless, which may not be to everyone's taste. For example, you won't really find a "bestiary" of monsters to throw at players, you'll be making them up yourself, maybe entirely on the fly.
The rules are all freely available online or in pay-what-you-want PDFs. There are three current editions:
FATE Core, all the rules of the game plus lots of extras, examples, optional systems, things like that
FATE Condensed, all the rules same as Core, but with most of the extras cut out and overall streamlined down to 60 pages from 300 or so
FATE Accelerated, uses the same basic ideas for its rules, but simplifies things down to the barest of minimums, e.g. dropping the skill list for 6 basic "approaches", simplifying the damage system.
Here's a link to FATE Condensed, as I personally found it easiest to start with: https://fate-srd.com/fate-condensed
One disclaimer: I haven't actually played it myself yet, but I have been prepping a one shot I'll be taking my D&D 5e group through this weekend to see if it's going to be a good fit for us, so I have been doing a lot of research!
It's an excellent game, hope you get to try it out even if you don't pick it for this particular venture.
Forgive some unsolicited advice, but if you ever do get around to it, the bit that was trickiest for us to wrap our heads around was the Touchstone role. They don't have quite as many mechanics to interact with as Power and Perspective, so it can be easy for them to feel a bit sidelined.
The truth is, though, Touchstone wields an enormous amount of power. Played right, they decide if the Kingdom lives or dies. Power and Perspective should absolutely be trying as hard as they can to court/persuade/win over/cater to Touchstone at every turn, because that is the only way to get the people on your side. Perspective could be throwing out softball predictions with a clear right and wrong answer, but all Touchstone has to do is throw their weight behind the "wrong" choice and it still turns into an agonising dilemma for Power. Can't rule over ashes.
