OK

My approach is one thing at a time, not shotgun as you suggest. There is definitely a front caliper problem. Since it is the most obvious, I will take care of that first and then see if the noise persists. If the noise persists then I'll work on a solution for that based on what has been suggested.

for now, things on hold till brakes fixed.

Sorry if I missed some rule about either closing down a thread or suspending it. Have no idea how to do that anyway.
