Considering your mostly interested in using your fist then you should do MMA but focus on your boxing skills,learn everything but focus on learning the punching technique practicing that and specialize in that area of fighting.It is good to learn other styles of fighting so you aren't as vulnerable to them for example if you learn grappling arts such as Judo Wrestling etc. then you will know how to defend against a takedown and will be able to keep the fight standing so you can use your punching abilities to win..Another benefit of training MMA is that you be exposed to many styles of fighting and so you will find out what your good at and what your most comfortable doing. If you cant find a good MMA place to train at then you could join the boxing gym learn how to box and get your fitness up then go to another place to train in another style.

Popular culture surely made it to promote such 'beautiful' actions. But you don't wanna think how 'aesthetic' you are while fighting. No.. You don't wanna know. You'll just need self-control, stamina, techniques, etc. The most effective movements. And that still doesn't guaranteed you'll win in every fight.

You can choose whatever you feel comfortable and fun with. Any martial arts will do as long as you really put efforts in training. It's for your experience anyway. But if you really wanna do something more applicable on the streets.. with punches, kicks, elbows, etc.. You can try MuayThai, JeetKunDo, etc. Or the combined ones like KravMaga, MMA, Russian Systema, etc.

My choice for you, would be MuayThai (good for training basic punches, kicks, elbows, knees, etc), JeetKunDo (to experience closer body contacts but still standing fighting techniques with punches, etc), MMA (you'll get more combined techniques experience) and KravMaga (Israeli's Self Defense Arts, 'anything goes' and 'everything is necessary' for street fighting). That's all from me.

Your choice.

I want to learn how to fight but not sure what style.

Im not those people who look for trouble.

I wouldn't want to use any kind of weapons to fight unless its absolutely necessary. I like how Bruce Lee or Jackie chan fight but im mostly interested in using my fist throwing punches. what type of style you think is best for me?
