I'd do whatever you can to explore things sideways in STEM-- discrete mathematics, weird notation, linear algebra, coding, earth science, meteorology, astronomy, etc. The reason is that the AP level stuff is so difficult to adapt because of the volume of written work-product expected and embedded into it.

Great Courses has some interesting offerings there-- might well be worth considering.
