Garuda has a Lite edition that doesn't include any of the theming, just vanilla KDE Plasma. It's been my daily driver for a year or two now, I really like it. What sets it apart are the GUI tools for system maintenance and tweaking, in which it'd be easy to mess things up, but they make doing common changes and adjustments easy. I don't know if that makes it good or bad for beginners, I guess it depends on the person.
