Hey, if I wanted to learn a bit about multi-unit tactics, what would be a good game to play?

Ideally either something up to two console generations old (so emulation is easy and solid), or PS4/Mac.

I'm not looking for an exhaustive simulation, just Baby's First Tactics. Ideally with some in-game hand-holding on basic tactical considerations because I know next to nothing...

I recommend Particle Fleet: Emergence and Fre Emblem as a beginner entry, as you get a bit more secure I would highly recommend trying the OpenXcom project.
The large amount of mods and features in the base game allow for a lot of varied tactics compared to modern games.
