Agree with @momofsenior1 . Admissions into highly selective schools is not a lottery with more applications = higher chances. You are a strong candidate, so shooting for some high reaches is fine. I also disagree with the views that well rounded students are at a disadvantage. Your EC’s on paper show accomplishment and active participation across varied but not totally unrelated interests.
I think the optimal strategy for you is to apply rolling to some good programs that are safety/low matches. Optimally your state flagship has an honors school or program. Start there, and maybe add another couple that are also affordable using the school’s net price calculator. Pick your top choice reach school and apply EA, SCEA or ED as allowed. Use ED if it is in fact your top choice and is affordable. Pick 2-3 reaches, 2-3 matches, maybe 1 more safety and get those apps ready to fire off after the EA/SCEA/ED decision date. In the meantime, if you get into a rolling admissions program, eliminate all schools you rank below it/them. Then depending on your EA/SCEA/ED decision outcome, either shoot higher (positive outcome, accept or defer for a school with a low deferral rate like Stanford ) or lower (reject), or just stop if you got into your top choice.
