Complementary challenges to the super sim challenge?

Hello guys!
So after a few years of not playing the game, I figured I could go all out this summer. So, as stated in the title, Ill be doing the super sim challenge(if there is like a super family challenge or super legacy challenge, please link as Id love to check it out) but Id love to also try out creating sims/refreshing the townies and getting into building. But, is there any of those type of challenges I can add to the super sim or any other game playing challenges?

Thanks for the help!
