@twins4heaven Hi! This will probably be swallowed in the comments but I might aswell give my two cents.
Ballet is a sport that is very well progressed, and since it is not so intensely physically demanding on the entire body, I'm sure you can progress quite well! Not to say people who do Ballet are weak, my older sister does ballet and sometimes lifts with me and can match my squat pound for pound.
Gymnastics is a very time consuming sport, especially men's gymnastics, and I honestly believe an hour a week will not suffice for any reasonable progress. As a certified coach and competitive athlete I've noticed the sweet spot for recreational male gymnasts is 4-6 hours, while for competitive gymnasts moreso around 18-30 hours a week.
From my experience growing up with my sister and my own training it seems ballerinas are extremely comfortable on their feet, while gymnasts moreso in the air. If you take gymnastics you will almost certainly run into minor/temporary skeletal aches while the worst I've seen ballerinas have are ankle-feet-toe issues. Men's ballerinas usually supplement upper body work with some sort of external training, but men's gymnasts are usually disporportionally muscular on their upperbodies.
I don't have any experience with aerial silks.
Dancing is fun
