That’s her choice based upon personal interests and career aspirations. I wouldn’t swap out AP Language, AP Calculus BC, or AP US History. AP ES might be the right choice for her interests depending upon what other sciences she has taken and will take.
And at some schools AP Spanish may be overrun with heritage speakers leaving SSL (Spanish as a Second Language) learners in the dust.
TBH, AP vs Spanish 5 is in almost all cases 6 of one, one half dozen of the other. You, your kid, and her GC can figure out the best option
