After looking through most of the posts, these are the 3 that stuck with me;
Firefighter/EMT Career option (Could be a single career that's split like the chef/bartender line, not even looking for it to be active)
Farming
Hobbies, Including bands (seems like it could be added using the clubs mechanic)
Bonus: The ability to answer a call of "wanna hang out" with "sure, meet in an hour?" so you can finish the thing your sim was doing before leaving, would also allow them to "get ready" like putting on an outfit or taking a shower which would add some realism to the interaction.
