I was thinking about putting it from its dedicated VM to opnsense as well. I just don't know yet what the security implications are and also my firewall hardware isn't too beefy so I have to play around with it for a bit.

Intel CPU RAM limits often are wrong for some reason. If a Mainboard coming with that CPU supports more, it'll probably work. I usually try to search forums to see if someone uses the same configuration and how much RAM they got to work.
Great to hear the yunohost migration worked. What's 35C?
I haven't tried that but good luck!
I'm personally using Prometheus Stack and like it, but I just check Grafana in my Android browser. I think Zabbix has an Android app but I don't know if it has as many possibilities as Prometheus.
Mostly the stuff in /etc/pve, plus whatever you installed in additional software
Oh, I wasn't aware of that. Not sure if there's a way to achieve that
Pretty cool! I also try to improve my documentation
Debian is kind of the default for many things now, so many guides etc will assume a Debian-like os but if you are familiar with other OSes you can try them just fine. Make sure zfs is supported by the OS properly if you want to use it for your SSDs (which I suggest).
If you are using Docker containers, you can migrate between OSes later relatively easy. Depending on how beefy your optiplex is, you could also use Proxmox as the base os and play with different VMs. Being able to easily snapshot the VMs is pretty great and for me has always been worth the overhead.
If you just want to install some apps directly on the server, I'd just go with Debian headless and set up docker, if you like with portainer or some similar GUI.
Interesting, I wasn't aware Talk has Text, always thought it's video only.
Moodle can also use collabora.
