My current setup is: Lenna as White Mage, Bartz as Knight, Galuf as Black Mage, Faris as Thief. I try to keep them in jobs that I feel their personalities suit. Lenna seems to be the type for a healer, Bartz is the main guy with a sword who protects his friends to the best of his abilities, Faris was raised by Pirates so she seems to fit the role of the rules-were-made-to-be-broken character, and Galuf is the old man who doesn't feel he's young enough for a sword so he throws fireballs instead.

Subject: What is your usual setup?

I guess the subtopic is: What kinds of jobs do you think suit which characters best?
