There are a lot of good calisthenics workouts that you can try, and I would recommend getting an adjustable set of dumbbells too.

Look at the thenx workouts on youtube to get yourself started.

Ideally you would work each muscle group once or twice a week with 2-3 days rest before you hit the same muscle group again. Most people do a variation of a push / pull / legs split to start.

Garage gym. Ideally bought before the lock down. Or anywhere with a floor strong enough for a squat rack and some weights.

The rack, an Olympic bar plus Olympic sized Ezy bar, a bench and an assortment of plates and ideally a plate holder and some thick rubber mats is all you need.

Has been an amazing help for myself through some tough periods lately. Also ditto on Stronglifts 5x5.

I bought a set of 20 pound dumbbells and a 50 pound kettlebell for less than $100 when I was in college. I got a pull up bar and some athletics rings a few years ago. I haven't had a regular gym membership in years. I can do 80% of what I want at home. It helps my mood a lot to do 6 sets of 12 pull ups and dips twice a week.

Start simple.

Buy some weights and do them at home?
