Anything that says QMK/VIA is supported in linux as you can define your own custom keys and develop/flash custom firmware if desired.
I run a K4v2 modified with QMK as my daily and love it for its compact size but still robust keyset since I actually use my function, navigation, and 10keys on a daily basis. My travel board is a K17 Pro because I wanted something a little smaller and low profile for use on airplanes and hotels.
Nearly all the Keychron boards offer hotswap and either white or RGB backlighting as well so you should not need to solder anything.
