i agree - it depends on your stats, your means and your objectives. Since you’ve essentially completed your Jr year, it is a little late for one to truly shape your ap by suggesting ECs, courses and such.
if you want to go to a popular in-state school, your HS probably has plenty of history with them to guide you through the application process. If you want to go to a small, selective OOS school and snag a bunch of merit scholarships, perhaps not.
You note in another post that you are from CA and are interested in the UCs, CPSLO, and USC. My guess is, your HS has sent lots of kids to each of them and can probably give you competent assistance working through the aps. There are probably UC essay workshops on your campus too. IMHO, it wouldn’t be worth the $$$ for a private counselor.
