It all went as planned thank you. Definitely not a job for the faint hearted!
Due to my unique project, it required some engineering thinking. Things I wish were different:
if you sold gates 36" or 48" with flat tops. Since I was on concrete there were parts I didn't need the ground anchoring system along with unused gate parts that I wish I could return. 2inch screws for hinge posts could be a little longer 3inch perhaps.

The diagonal support bar from. corner to corner has two nuts and bolts that could be drilled to not face inward toward the vinyl board and push the bar away from it. Perhaps the columns could have base covers for a concrete application, much like pergolas do.

Overall I'm happy with the outcome and privacy the gates offer!
