All 4 of those schools appear to have vocal performance studies based on opera.
I think the dual goal of vocal performance with contemporary music. and wanting to be part of a college with access to good academics, and integration with non-music students, really narrows your choices.
Your husband didn’t enjoy being in an all-music environment. How would your daughter feel?
Thornton, Frost, Berklee, New School, Belmont, Loyola New Orleans have all been mentioned on here for contemporary vocal and songwriting. Of those, only Thornton and Loyola would seem to meet your criteria. (Here is Loyola Popular and Commercial Music | Loyola University New Orleans (loyno.edu)
If you daughter doesn’t want to do opera, I don’t see why you are visiting the schools on your list but maybe I am missing something! Puget Sound is a possibility Music | University of Puget Sound
I think your daughter could also do well, if her goal includes being in an environment that is not all music, at any liberal arts college where she could do music as a major, or as a continued extracurricular. There are many many colleges where she could thrive musically, but a BA in music does mean 2/3-3/4 classes that are not music. These are generally non-audition and she would submit a music supplement. She could choose based on size, location, and “vibe.”
But even BA programs are predominantly classical so you have to look closely to see if popular or contemporary music classes and lessons are offered.
