Just to really clarify: there is no real performance difference between "gaming" distros and any other one. They just have some stuff pre-installed you can just install yourself. The only real thing you want to be aware of are standard distros vs immutable distros. I would steer clear of immutable until you're more comfortable in general.
All that being said CachyOS (Arch based) is fine, but skip Nobara and just go stock Fedora Gnome or KDE to skip the prepackaged customizations and just get a clean experience.
