As others have mentioned, an active day care career for adults would be neat, and also quite easy to set up: You're in a house with a bunch of babies, toddlers, and/or children, and your tasks include working on their skills and character values, helping them with homework and so on, while also keeping everyone fed and entertained. Sadly, I don't think we'll ever get this because the best opportunity to release it (Parenthood) has already passed.
On top of that, I've always wanted at least one job that focuses on the Handiness skill, and I can see that working well as an active career, too: As a mechanic, you spend most of your time at the office doing the usual active career stuff as well as crafting wooden furniture and upgrading appliances that your company sells, but similar to a doctor, you also make house calls and repair or upgrade objects as requested.
I can imagine a couple of magic jobs coming with Witches, but I won't get into that now because I'm afraid I'll get carried away too quickly...
