How do you usually play Careers? Go with them, Work from Home or Rabbit hole

As the others have said, it depends on the Sim. Although I do have a preference for unemployed/self-employed and just have my Sims garden all day, or paint, or authenticate and sell artifacts, etc.
When I do play a career that has the option to work from home or go to a rabbit hole location, I usually vary depending on the Sim's needs, what else is happening in the household, whether they have other things to do. It's been some time since I played an active career, but I always join my Sim at work - their progress is so much slower when you send them alone. And joining your Sim at work is the main part of the active careers.
