For B’nos Avigail, check the website. I don’t know whether or not websites are an accurate way of telling about seminaries, but at least it lets you know what the school’s goals are and something about the type of teachers. The best way is to speak to girls who are or were there.
From the website, it sounds like it fits what you are looking for.
Machon Raaya, Darchei Binah and Ateres might all be good options for you. Possibly Binas but I don’t know enough about it.
I’m a bit confused about what you are looking for. From your description of what you are looking for, I wouldn’t think that Meohr is the best fit for you. I would think that all the other schools I mentioned fit your description better (probably B’nos Avigail also).
