big hugs and huge kudos to you, for doing all you can to manage your pregnancy and birth in the most sane, informed and humane of ways possible. This must be so hard to deal with! Keep your courage, and your calm--trust yourself to make the best possible decision given the facts when labor time comes. Feed yourself well, get plenty of rest, go for walks and whatever else helps you feel at ease and nurtured--this kind of stress can really burn the calories and eat up emotional reserves, so be very kind and gentle with yourself, restore yourself at every possible turn. And know that you are doing 2 of the hardest kinds of work at the same time: growing a baby and dealing with a huge stressor. (But hey, you're a woman! You can multitask AND you have other superpowers, right
I think that it's very possible that either your baby will turn to vertex, OR will put herself into a better position for vag breech delivery. Some babies dont' do this until mom is actually in labor--so, if your final decision is to go to the hospital on birthing day, INSIST that an u/s be done BEFORE you go to OR.
I also just remembered a story a friend told me about her sister's breech csec: they also could not find a vag-breech provider, and agreed to surgery. It turned out that their baby had a congenital defect of the bones of his face/nose; vag birth was very likely to cause damage while csec prevented damage and allowed medical assistance over time to help correct this unusual condition (he was otherwise just fine). It is not the only such story I've heard about a breech. It is true that for some women (and this can run in families), breech is just normal for them. For some, babies get into breech because of underlying maternal/familial stressors/fears; and some go breech due to uterine issues (such as big fibroids or a bicornate uterus) or baby-issues such as my story illustrates.
I wanted to say all this because at this point, you don't know why your baby is breech. Maybe you never will. I just want to encourage you again to keep your courage and intelligence and instinct and calm--you can make the right decision for yourself and baby, even if you don't know 'why' until later. From what you say, I believe you are now doing all the right things. Keep your center, breathe deep and breathe again--if your own or family fears are impacting this baby's position, then acknowlege that and keep seeking peace. I don't even think we have to entirely "cure" our fears prior to birth--we just have to acknowledge it, and continue to move forward in spite of it--which is the definition of courage and trust.
We can also talk to our babies about fear and stress: 'Yes, baby, there is some fear here, some stress...but you let me manage that, I'm your mom and that's my job. I'm going to do all I can to keep you safe. You are safe in my love, it's ok to come out and be here with us, we are taking care of you now and we are going to keep on taking care of you.'
sending you prayers for calm, trust, strength.
