I haven’t gone through the college admissions process yet, so take what I say with a grain of salt.
You probably don’t need to worry about your objective stats, looking at your ACT and GPA (I don’t know how the 100 scale for GPA works, but your number higher than the other applicants I’ve seen who used it). I think that you have a really varied lineup of ECs, which is fine as long as you’re especially passionate about one or two of them and can show it in your essay. Even if you don’t have an “official” leadership role for some of your ECs, I think they’ll be able to look past that as long as you elaborate on your involvement. I was personally kind of a goof during my freshman year as far as ECs go but picked up the pace later on, so I understand your concerns.
