Brazilian Jin jitsu question?

Hello, I recently have had to stop boxing because of a stress fracture in my foot, it has healed some I can walk and bear weight on it, but can pivot, or really press off of it, so I was wondering if Brazilian JJ would be a good alternative until my foot heals or I have surgery to correct it, also I was wondering about the fighting style, is it mostly wrestling submission moves, or are there stand up fighting techniques as well, thank you
