Might take a while to get to it. But I will post up results and findings. I too like seeing how issues got resolved on here. Helps folks in the future.
I've got a couple of O2 sensors ordered already. So I'll swap the one that throwing the code seeing as it needs doing.

You may as well change out all the O2sensors you have replacements for at once.
As after rereading your first post I see you have codes for adaption range issues on both banks.
Those codes could be caused by the SAI issue.
Or the O2 sensors could be causing the SAI issue.
But with 175k miles if the O2sensors are original then replacing them first may be more prudent.
Easiest things first.
