I expect the guidance counselor at your private school will be the best resource in terms of learning where students with your profile should apply.

My kids found the scattergram plots to be somewhat helpful other than for the highly rejective schools (which turn down students with perfect GPA/SAT). The scattergrams we had access to did not note things if candidates applied ED, had hooks, etc. so we regarded them as a very general guide.
