Agree with @one1ofeach. Very solid academics but the EC’s are short for school leadership type positions such as an officer in Student Council or NJHS. But, you have a well developed resume overall.
As you read endlessly on these boards, many of the schools on your list accept roughly 18%. So basically your resume is excellent. You will (IMO) get in to several of these schools. You are now just playing the odds for who they need for their class puzzle piece.
Chances you get into one of these schools? (based on your evidence) 90%+ (I actually believe it is closer to 99% but keeping expectations in check)
Chances you get into your #1 choice? 20%
Basically you are in great shape, not much else to do other than write well crafted essays.
