Helpful, please see an online Teshuva of Rav Yehudah Henkin who shows that there is only one Rishon who holds that chibuk vnishuk is yehareg val yaavor and that is Rabeinu Yonah.
You have also not addressed how the Amora in Kesuvos 17? picked up the kallah. How was he allowed to be over on a yehareg v’al yaavor?
