AP Psych is widely considered to be one of the easiest A courses so I don’t think taking the course online or not would move the needle on admissions decisions. And FWIW my D took AP Psych in HS out of interest (she went on to major in Psych in college) and her college did not give her credit for Into. to Psych because the AP class had no lab component.
Again, I’d focus on doing as well as you can in the HS classes you have and spending time on ECs you care about.
If there was a scheduling conflict that precluded you from taking some more rigorous classes ask you guidance counselor for address it in his/her recommendation letter.
