ASB vs AP Physics 2?

Some background:
I am going into my senior year next year and I need to decide what I am taking. My schedule so far:

IB Language Arts HL
IB Math SL
Theatre Arts 3* HL
IB History of the Americas HL
IB Biology SL
AP Physics 2 OR ASB

(*my theatre class is not weighted and has brought down my gpa. Next year is my 3rd year, but I needed to take 3 years to take the IB HL Theatre test. I was considering dropping it and taking AP Physics 2 next year, but wouldn’t that mean I virtually wasted two years taking Theatre 1 and 2? Please help with this as well!)

I am taking AP Physics 1 right now and am enjoying it, but I have been wanting to do ASB since freshman year, and next year is the first time I have a free spot. However, it is impossible to get a main position (like president or VP) because it will be my first and only year, so is it even worth it? Will it look bad to colleges? Is AP Physics or AP Environmental Science a better choice? Thank you!
