Maybe something other than Ubuntu? Ubuntu is past its prime, it used to be good, but as other distros got better, it didn't, leaving it outcompeted. I'd recommend Mint, Bazzite, Fedora, or PopOS, but that's just the sentiment I'm getting from the community; I myself have only used Ubuntu and openSUSE on desktop, and have used Debian in VMs for stuff.

Currently I use openSUSE, which I like, but it's not a beginner distro. It's quite universal, but that means not targeting beginners nor advanced users specifically. Debian is also like that (Maybe I'd use Debian if it had a good rolling release, but Debian Unstable is for testing and not meant to be stable, as opposed to openSUSE Tumbleweed which is probably the stablest rolling release out there, with a good QA system, because it's meant for daily use.). I've also heard that Fedora is universal like this. So why is it regarded as so good for beginners? Maybe openSUSE is actually fine for beginner usage? I don't know. The install would probably require the guidance of a Linux user though.
