You are on the right track.
Note that for Cornell you will lose the legacy bump if you don’t apply ED.
IMO you shouldn’t be focused on pinning your hopes on schools with such long admissions odds. Having a dream school is a recipe for disaster. Enjoy HS. Do the activities that speak to you. Next year start thinking about and exploring creating your match and safety list. There are plenty of amazing schools out there where you can thrive and be successful.
