One point of confirmation for wife's journey post ILR is that it makes zero difference how/when I became a bitish citizen for her own naturalization. As I am (and she would meet the other requirements) she could immedaitely apply for naturalization/citizenship immedaitely upon being granted ILR (not have to wait 1 year).

I agree with your understanding. What is the question?
Have you reviewed the AN guidance?
