What soccer position is best for me?

Well I'm short, like 5'1 but I'm really fast. I have good short passes and occasional good long passes. I'm not so good at like tricking or juking people out but I can do it at times. I like to play both defense and offense and according to a lot of my friends I'm a good assister but I can't decide if I should play as a right or left fullback, a DM(focus more on defense), or a CM(box-to-box where I run back and forth to help the Defense and Offense). What do you guys think if best? Also I like to take shots from the outside of the box but since I'm so little the shots aren't that powerful sometimes
