The most important thing with exercise is finding something you enjoy doing - you're less likely to say "I don't want to" to something you have fun doing! I feel that everyone (outside of a doctor saying otherwise) should do endurance/cardio and also a form of strength training, but how you get that is up to you.
Deciding how social you want to be is a good way to start. Do you enjoy the solitude of a morning run with just you and your thoughts? Or is an interactive group more your style? What about competitive team sports? Do you like being around people, but not necessarily interacting with them?
One more thing - you're on Day 3. Start slow when it comes to adding exercise. Trying to do too much too soon can lead to burn out or even worse, injury. Allow at least one day of rest between high impact cardio or strength training, and possibly more if your body still doesn't feel ready to do it again.
Do something everyday that your future self will thank you for.
