Mage Knight is fun, but you should definitely hold off on it for now. Its more of a hand management card drafting game with some exploration.
Dungeon Crawls that go well solo? I'm maybe the biggest Shadows of Brimstone fan here and will always recommend that. It's very similar to the old Warhammer Quest (which has an app and a PC version). It has minimal campaign elements, but your heroes level and grow from game to game. Very RPG like. But there is a TON of stuff for that game, and it can be daunting for a newcomer to get into.
You can also check out something simple like the D&D Adventure games. The newer ones have more RPG elements and are quite easy to setup and play.
There are a lot out there, but it depends on what theme and "mechanics" you're interested in.
Yea probably the simpler the better, especially need something that I can "pause" play or finish a session quickly and put it away and get it back out easily. The D&D ones are just called D&D adventure?
