AP classes that you could look into are of course the field you want to get into- technology based classes-if that's what your school offers. Computer Science classes, some Algebra classes (up to advanced levels) and some other advanced Math classes could be taken in High School to better your chances.
The main reason why students often take AP classes is to make their applications to colleges and university shine bright. Most schools require 7 to 12 AP classes for entry to that school.
But tldr focus on growing your coding skills and keep up with latest tech trends like cloud computing. Dont worry too much about AP courses
