USNA cares about community service. 77% had some form of it in the Class of 2025. They don't really care about how it is done. It can be through Sea Cadets/CAP, a school service club, Boy Scouts (my personal route), external service organization, church, etc. I'm not going to say it is essential or not since I don't represent Admissions. By the looks of it (77%), it is desired, but not absolutely required. That said, USNA like leadership in those roles because it suggests experience, talent, and potential to be a leader in a service-based organization (such as the military).
I'm not implying that you shouldn't join a club. Community service never goes out of style. What I was more driving at is that you stated you're going to join all possible clubs. That isn't a recipe for success. You won't have the time and if you have a bunch of President titles earned within a year or so, it just comes across superficially. That's all I'm saying. But if you join one club, for example, become President, and make tangible differences, then that's fine. You now have some ammo for an interview/personal statement. "I saw the value of community service in high school, joined club X, liked what I was doing and wanted to improve the organization, became president, and made Y improvements." That is an answer that I'd want to hear as a nominations committee member or BGO. You could have a profound experience during community service that you could write about as well.
