I run Silverblue on 2 devices (my main computer and laptop) for half a year. It works and I didn’t have any major issues with it. Though as you might have experienced with other immutable distros, some things like configuring gdm might be a bit more work. But for most things there is a flatpak. The only software that couldn’t be installed that wat was my vpn.

If you want to try out something new, NixOS or Guix might be more up your alley

That’s funny since I didn’t even know what Linux was when I started my CS education, nor that there were so many services you could host yourself. I was egged on to try Linux and (eventually) get a small homelab by my uni friends, who were probably more like you
