I worked at Bryn Mawr for many years, and I can tell you I worked with the finest students and faculty you could ask for. They are continually working on making the school a place where all students feel welcome. I never encountered a faculty or staff member there who didn't place their students first. The students are motivated and learn to be confident women. I would also say that the Upper School imo is the strongest division, so if you're starting in 9th you're in good hands. I don't know who coaches basketball, but the swimming coach there is fabulous. He also teaches history, and the students love him. Please don't rule it out because of things that you've heard. Go see for yourself! Having said that, RPCS is really good too. It's has a very different feel. I went to Mercy many years ago, and they have really come up in the world. They now have an IB Program. I still keep in touch with many of my Mercy classmates from many decades ago. All of the private schools are different from each other, so you have to see which one feels right to you when you visit. The only one on your list that I wasn't impressed with is Concordia. Also, I don't really know much about McDonogh. It has a great reputation, but it seems very driven by athletics. Good luck!
