I was going to suggest the same as @dramakid2. Additional ones to consider are Episcopal and Blair. The nice thing about your geography-constrained list is that there are several schools known for their “kinder” cultures, yet they all are different from each other. Your D will have ample fodder for coming up with a good idea of what she wants her high school experience to be and then to make it so.
Btw, having watched your recent college search, it’s clear you are a researcher and a planner. Don’t worry about feeling late to the BS game – you’re not! There’s plenty of time still to go through the process thoughtfully.
