>What about the style of lunar city we have in Gundam?
It's essentially a space colony except 0.1G.
The elephant in the room is still whether mankind can live under a gravity other than 1G for all their life without having (generational) health problem.
If you've heard of it, making the whole city rotate on magnetic bearing would be costly, complex and impractical.
Mankind typically settle somewhere because they can't reach (or make) a better place, physically, politically, or because you absolutely need human there and you can't control remote robots because of latency & interface.
The moon would allow Lunar elevators >>23420809 that reach a good place for space-habitat so you could live in orbit and descend in vacuum-maglev train to work in some lunar mines or visit some biodome with gigantic lunar tree or something.
If you can bioengineer humans to live anywhere, then the Moon 0.1G, or Mars 0.3G gravities can be unique resources that appeal to your lifestyle.
Whatever the case, you would necessarily have access to space for all resources not already/easily present around and other reasons.
A low-gravity moon with no atmosphere to bother magnetic launcher would definitely have easy access to space.
