As someone who did all of it and ended up majoring in engineering, in my opinion calc is the least practical of the senior high school math courses— geometry and data management (stats/probability) are both much more likely to be useful to normal people doing their taxes, understanding elections, fitting furniture into rooms, whatever.

That said, I think calculus is helpful in the way that learning a niche programming language is helpful: it teaches you about new kinds of abstractions, how to think in a different way, and gives particular language with which to talk about that kind of thing.
