I'm not new to Linux but I am new to gaming on it (used to dual boot). I installed steam and the games I've tried just work. Experience will be better on AMD but even Nvidia is getting there these days.
My understanding is that you shouldn't try to install steamos on a desktop computer.
I've heard good things about EndeavourOS. I've never tried it myself but people say it just works. It's based on Arch linux (SteamOS is also based on Arch) and seems to be quite easy to use.

Can't help with the OCD but maybe try finding an laptop to install linux on first. It's how I learned.
