True there is no beating the arch wiki

There is also Xero Linux

I mean I don’t think it’s the same as red hat at all because they are not making it closed source.

I think there will be even more support for anti cheat games and there is no way NVK even on its supported cards will have performance parity with the proprietary driver.

I’d recommend opensuse tumbleweed. I would suggest Debian but it moves too slow (updates) for gaming. I think arch is good but you will have to want to learn a bit more about it. Tumbleweed falls closer to Debian with stability and still near arch as far as frequent updates.

If you care about rgb just look at supported devices and brands here https://openrgb.org/devices.html This is an extremely long list so just find a keyboard you like and see if it is on the list.

Any keyboard is going to work. As Ipacial said not all rgb stuff will work but basically any major brand works with open rgb at this point. I personally have a razor keyboard that I can control the lights with open rgb. I have a Logitech mouse that does not have rgb and I control the dpi with solaar.
