Here’s an update. I followed most of your suggestions. Tightened the cleats, lubed and tightened the pedals, chainrings and other driveline components. Made sure the FD cable was out of the way. Checked the seatpost and more.
Problem is is still there. It doesn’t show until after about 10 miles but it’s still there. It’s more prominent under heavier load and relatedly up hills. The sound is between a creak and a click and is worse as the load increases like in the big ring, 13 tooth sprocket. Any more thoughts?

Does the click occur at the same point in the clock relative to the pedal positions, and if it is, does it change if you change gears ? Or is it completely random when the noise occurs?
To fully eliminate pedal/cleat possibility, you could swap in some platform pedals and see what happens.

Did you try 1-legged cycling?

I can’t imagine it’s the pedals or cleats. I used the same combination for 500 miles before this issue started.

Well, YMMV, but recently I was convinced that I had BB creaking and it turned out to be in the stem. Yeah, under heavy load you may be leaning on the bars more, and the front end becomes suspect.
When I took the bike into the LBS, the mechanic said, "everybody always thinks its the BB, but it could be anywhere."
And that's the point, it can *sound* like it's coming from the cranks or BB, but it could be anywhere.
Unless you are really good, I suggest a trip to the LBS.

You sir or madam are in my debt. If you are in SE Michigan I owe you a beer or 2. There are others with the same suggestion if I recall. Thanks to you all.
I feel foolish, dismissing these suggestions, but it finally clicked. Loose skewer, flexy rear triangle, especially under load. Duh! Just came back from a ride and the angels sang once again.

Glad I could help, enjoy the quiet.
