I haven’t been a mint user for a while, but the fact that the mint folks specifically release MATE/XFCE versions is a good sign that they are tested for compatibility. You can try those versions on liveusb, too.
I’m guessing here, but the “less terminal needed” parts of Mint are probably specific tools and GUI settings managers they have put together to be more user friendly. if you search something like [name of Mint settings manager or tool] XFCE compatible, you’ll likely get an explanation. You might want to check out their Matrix chat room with specific questions: https://app.element.io/#/room/#linuxmint-space:matrix.org
Organic Maps is a good app that also lets you do some editing. I like the interface better than osmand
