Need help selecting online AP providers?

I am a recently graduated high school senior taking a gap year before attending college (ultimate goal is to subsequently attend veterinary school). I am taking said gap year to further gain internship and service opportunities in a variety of different veterinary and animal-related fields, as well as to take some more APs not offered by my school (I also plan on taking college-level calculus at a nearby CC).

The APs which I am most interested in are as follows, although I am ultimately going to choose to take no more than 3. I plan on taking the AP examinations come May as well.
AP Biology
AP Environmental Science
AP English Language OR Literature
AP Art History
AP US History
AP World History.

I have looked around a lot already, and have found that FLVS, UC Scout, BYU, and Apex Learning are all well-regarded, generally speaking. There are many others around, such as Ogburn Online School, Laurel Springs Academy, etc., although I have not heard as much about these. Could any of you that are able kindly speak on your experiences and make suggestions for not only online high schools/AP providers, but also in terms of specific online AP courses offered by different providers? Thank you!
