I try to match them with the sims and their environments. For example, I'd rarely choose conversation, lifeguard, or fisherman when not living in Sulani. If a sim has a degree, I try to match a job to it.
However, I do tend to avoid the extra active ones unless it is my main sim or I just want to play one specifically. I am usually more focused on other overarching things than just their careers, so having to travel with them every day is too much of a nuisance unless I wanted to play it specifically. Plus having a bunch of Sims in different active careers is quite the hassle. (I nearly always play a household of eight.)
