What martial arts should I learn?

I was looking for some martial arts to study. I wanted to study some that teach how to disarm people from various weapons, defend against multiple attackers, hand to hand combat, etc. Basically things in a street fight, I want to defend against. I was looking to study Ninjitsu, Hapkido, and MMA. What do you guys think. Or I was looking at a self defense practice like in the miitary, could you guys tell me some good ones I could use to neutralize my opponents, like Krav Maga. If it helps: I am 14, 140 lbs, muscular, fast, I think I am better with Kicking compared to punching. And I kinda like hand to hand combat stuff better, not just throwing punches and elbows.
