Honestly, having only seriously played around with Ubuntu a little bit a year ago, CachyOS has been nothing but smooth sailing for me. I would consider myself pretty savvy, but with the built in tools provides even a casual user should be able to get up and going.

I use paru instead of pacman, so I can get AUR packages easily, and outside of running a 4 letter command and following the prompts, that's just about the only thing I've had to do in a terminal.
