That class is likely to be a more advanced, college-paced version of the physics class she took before. Since she completed both Calc AB+BC, she may enjoy Physics I and clearly has the math ability for it, so I would indeed request it.
As for math:
Discrete Math one semester, Linear Algebra the other? Or calculus-based statistics&probability? All in all, she can pick anything 
Make sure she reached level 4 in Spanish (would be 3rd or 4th semester Spanish in college depending on how fast the college classes are and how in-depth they are).
