Gadol, Stern is a good option and I know many people who had good experiences, but, again, for those paying full price, way overpriced over quality. I hate sound so materialistic, but may I use a car analogy: it is wrong when all I need is to commute to work and I am forced to buy a Ferrari “like everyone else”. I understand that contrary to regular colleges, YU counts high/elementary school tuition as part of parent burden, so it may work reasonably for many.
Could you say more about limudei kodesh groups for college women – this sounds like a reasonable approach.
As to “where”, there was a striking article in something like OU magazine ~ 30 years ago by a non-NY Hillel Rav at a big university – where, contrary to his financial interest, he strongly advised parents _NOT_ to send their children (both boys and girls) out of town for college, saying that this is an American tradition with no Torah support. This is the age where you have a chance to teach the kid – and you are sending them away?
