I’m not familiar with any of them and hopefully someone is. However, if I were you I would look to see who is in charge of priestly formation. If it is a nun or laywoman, find another seminary.
I’m a female and I’m sorry to say so, but priests should be responsible for the formation of young men, not nuns, most of whom have a progressive agenda, which includes pushing the women priest agenda. Thank God you are looking for an orthodox seminary because you want to be formed in such a way as to support the magisterium, not challenge it at every opportunity. So many of these seminaries have been corrupted that I would research thoroughly.
All kidding aside, that is one piece of criteria I would look at - who is forming the priests?
For more reading, consider this. It explains how the “sisters” have been filtering out orthodox young men who didn’t pass their litmus test, or making life miserable for those they could not filter out. It is utterly shameful.

Furthermore, you might inquire about their devotional practices and see what their reaction is. Do they have adoration? Do they encourage the rosary or other devotions or do they consider this “rigid”?
