Are they all PGS tested? If not, you might want to do that to see if they are all viable... chances are some will not be. You can probably get a bulk rate so it shouldn't be super expensive. I think embryo donation is a wonderful gift you can give to another family though there are some implications for your kids since those will be their genetic siblings. I am in a similar boat but only have 1 viable embryo frozen so the choice is a bit easier for me.
