If finances are an issue, research need-blind and meet need schools, but there are others that may be affordable.
I almost feel as if you have done too much. Your activities don’t feel cohesive to me somehow. I found your scuba diving to be interesting.
Apply where you want but yes, look beyond Ivies (including little Ivies, which you can google). Applying to a huge number of schools is very stressful and you look very busy. Make sure to get enough sleep and down time!
