What Position Should I Play?

A few months ago I started playing League of Legends because a friend suggested it. As this is my first PC game, I struggled early on and felt lost on how to get better. I took an early liking to jungling because I enjoy having the mobility. I am closing in on level 30 and am still looking to main a position. Lately I have been playing mid and adc, and are enjoying those positions as well. Looking at the champions I enjoy to play, I enjoy to play a variety of different champions so I don't have a clear favourite position. I am generally a more aggressive player and normally play physical champions but have recently been practicing with ranged ones. I have a natural understanding for the fundamentals of the game (warding, objectives, split pushing) but when it comes down to a teamfight, there is so much going on that I usually make a critical mistake. I can only hope to get better by practicing, but I am still not sure as to which position suits me best. To sum it up, I am good with the game mechanics, but struggle with applying them. Any champions/positions does it seem like I will enjoy?
