I believe learning to get comfortable solving problems and learning any language can be a benefit. The specific language is not as important leading up to college.
I got interested in programing by experimenting with HTML and custom DOS prompts (old). When in High School, I was lucky enough that classes were offered. The language was Turbo Pascal whichI have yet to encounter again in school or work. Still, when I got to college and started having classes in C, C++, Java, etc. this wasn't a barrier. I had exposure to programming concepts and solving problems. What followed in college was more in depth learning of the syntax/semantics, algorithms and generally more learning how to learn.
In short, learn what most interests you and will keep you engaged.
Best of luck!
