I have a friend whose mother has a law degree but then chose to stay home because she had no need to work. Her husband made enough money that it wasn't necessary. So she started doing work with a lot of charities. If Victoire does choose to stay home I could see her working with wizarding charities, especially after all of her children are at Hogwarts.
