Hellllllloooooooo telekinesis! It's always been my go to answer for questions such as these. The ability to just move stuff with my mind is one that I could definitely abuse if I wanted to... but could also make my life so much easier if used properly! Flight would, admittedly, be kinda cool, but I wouldn't be able to use it without people spotting me. Telekinesis, however, could be used in lots of subtle ways, which would be a lot better for me!
