I think it’s a toss up. Personally, I’d take Latin as it is fairly unique in the sense that far fewer take it. ( In addition, most who take it are pretty serious students). Spanish is MORE useful but since you are Hispanic you likely have the spoken component of the language down ( is that is largely the most useful part). Having both Spanish ( from your heritage) and Latin from school makes you most impressive IMO. If I were you I’d take Latin and bump up my Summer studies by studying for Spanish AP over the Summer. That way you would have both.
It also depends on your direction. IF you are leaning towards a helping/business field Spanish might prove more useful. If you are leaning toward medicine it’s a toss up and if you are leaning towards law, politics, history, I’d go for Latin.
Of all the things I studied, the only thing I wished I had studied and didn’t is Latin. It’s the key to tying multiple subjects together. And it’s purely intellectual. That might be why it is a dead language.
