Im looking for a new expansion, any tips or suggestions?

Hello, I usually play as a family and am not sure I want to separate members and play as one and then switch back to another, but I am open to the possibility. I own Cottage Living, get together, Cats and Dogs, Seasons and City Living... and some packs and stuff. I'm looking for a new expansion that will add a good world, and just good in general. And if it fit my play style, that would be nice as well. High School years, and I think College expansion may not fit me. I just got a girlfriend moved in and am working on skill building for her, I work in the garden and am a musician, she just started as a babysitter. Get to work is on my radar, I could switch to one of those jobs, other than that I don't know. I'm just looking for a good world and am interested to hear what different expansions add to gameplay. I'm also interested in just buying a pack or two instead of an expansion. But I really do want that new world. So, what is a suggestion, and what has a good world to live in and explore. Packs and expansions are on sale now so I'm thinking of buying something. Lastly Get to work, Eco lifestyle and get famous are on my radar, but I've heard get famous has a very small world. Eco Lifestyle I'm not sure of, does it have a world you can live in, and have new lots and sims. Also is there anything offered in that expansion that doesn't require me to stop what I'm doing with my family and go do something else in that expansion and same exact question about get to work. I'm also interested in all packs and etc., if you have any information that can give me insight, I would much appreciate it. thank you for your time. Oh, sorry to make this even longer but it might be wise to mention some of what I own. other than what's mentioned above
-parenthood, toddler stuff, kids' playroom, paranormal, dream home decorator, pet stuff, I can't think of the rest, but a few more.
