With your preference for playing just one family, I ruled out Get To Work.
I like the pack, but when you play a sim with an "active career" you need to follow that sim to work, which means all the other sims in your household are out there on auto-pilot the entire time just one sim is working and the active career jobs from the pack have more work hours than base game careers on top of that. I've found that this makes active careers rather unsuitable for sims who are raising a family.
You do have the option to just send them to work, like a normal rabbit hole job, every day though. But that rather defeats the purpose of the pack in the first place.
So, now that I've clarified why I ruled out Get to Work, I voted City Living because it just adds 'more' to the game when it comes to what you said you enjoy, plus having apartments and penthouses for your sims to live in is freaking awesome.
All the additional homes (apartments) is also a lot of fun for the aspect of "micromanaging the community" which you mentioned. It gives you places for sim households that don't really make a lot of sense owning a house. Households which are all friends-as-roommates, for example, make much more sense in an apartment than a house (at least to me).
All that said, all 3 choices are solid packs as far as I'm concerned, so you wouldn't go wrong no matter which you pick.
