There's also a KDE version of Nobara. I use it myself and it's been great so far.
Simualting a German accent I guess.
Prey (2017) has a great level design. It's one giant interconnected space station that can also be explored from the outside. Different areas all feel very organic and actually liveable.
I use Nobara for a console setup like this and it works great. Boots straight into gamescope, feels just like the steam deck itself.
