Seasons is a great pack, not just for the seasons but also for the family play additions. Building snowmen, having snowball fights, having Thanksgiving and Christmas dinners, rainy days to hang out in front of the tv, etc. It's always been my favorite pack and it's no exception this time either.
If you like occult gameplay, I think RoM is a really good pack. I absolutely loved Supernaturals, and I also really love RoM. I've been playing almost exclusively with witches. There's a ton of spells and the different types of spellcasters are nice. The realm isn't the most exciting place it could've been but I almost never go there and still absolutely love playing with this pack.
Of course, as a family player, you might also really enjoy Discover University. It gives you a great reason to have your sims skill up and get good grades in the hopes of getting them a scholarship and maybe even allow them to start a distinguished degree instead of a regular one. I really think Uni is a super fun pack, even if I wish we'd only need to take 10 instead of 12 classes (or 12 for distinguished and 10 for the others). Because it's really hard to have multiple sims get A+ grades if they don't live in the same household and/or have too many electives.
Given your description, that's what I think would interest you most. However, I strongly suggest to anyone to also consider Get Famous because it adds so many layers to jobs as a whole, and I think the acting career is brilliant. I never even wanted this pack, and I ended up loving it so much, it's still in my top 3. Same for Dine Out but then I don't have many issues with it ... you might though so I won't suggest it quite as strongly :)
