Another vote to expand the list. The schools on your list get tons of applicants and you could very easily get shut out of all of them. Needing lots of FA means you need to bring something to the school it doesn’t have. Maybe it’s that you represent a SES class that is underrepresented. Maybe it’s your musical talent. Having good academic credentials is a given, though.
I noted your sea scout activities. Have you looked at Tabor?
Mercersburg and George have some of the highest % of students on FA so could be worth a look, and George has very strong programs for coders.
You would probably want to talk to each school about their position on the 10th vs 11th decision. Most would encourage 10th, I think, but you will need to be able to articulate the pros and cons for yourself and your situation.
