Mabox has an option at setup for Chromebook keyboards but i find binding from a regular keyboard less of a pain. My one real issue was the sound card, but SOF ( sound open firmware) fixed it immediately.
Mint is basically perfect, i just wish their xfce edition was based on Debian And not ubuntu. Mint + debian = the tops. Another one to consider is Sparky Linux. I heard good stuff about it. https://sparkylinux.org/
