CachyOS might be the easiest one that gives you something decent. It's basically an Arch Linux with slightly better compiler optimizations and tweaked kernels. Also a tweaked version of proton in the core repos.

Started by a German dude so EU++ or something. And of course it's based on Arch Linux, which was started by a Canadian dude.

It's on top of distrowatch too, but I have no idea what that implies.
