I hope am not too late for this. If you’re looking for a consolized PC experience with Steam and all of its quality of life features, check out ChimeraOS.
It is based on SteamOS3 and adds a lot of extra features such as GOG and EGS integrations and built in emulators.
It also has a desktop mode for a full featured Linux experience. Keep in mind it’s an immutable distro.
Also, it uses Arch btw. Sorry just wanted to say it for such a long time now 🤣
