Hi there! If you send over a DM with your VIN and Ford dealer info, I can look into your concerns on my end.

I have a 2022 3.5L Ecoboost (18k miles) and have experienced the same although not as hard to leave marks on a gravel road. Curious if you have also noticed whether or not your trans skips/passes 2nd gear on up and down shifting?
Yes the trans skips from 1 to 3 upshifting but I'm not sure about 3 to 1 down shifting. 1 to 3 has been like that since new. The marks on the gravel road was the last time it did it and that's what prompted me to post on this site.
I'm thinking the 2nd gear skip is there for normal driving but towing a light load or heavy acceleration might use 2nd. Like I said, my truck has skipped 2nd since new so I think this is normal. What isn't normal is the clunk.
I brought my truck in to the dealer, the tech drove it with a 2000 pound trailer attached and without the trailer attached and could not make it clunk. That's always the way it goes for me. We discussed the possibility of a bad valve body but without something showing up on the tech's computer that was hard to prove. They said there is a TSB on the trans and did a reset on it. It's still too early to see if that reset had any effect. With only 19000 miles on a 2021, I don't drive it much, so only time will tell if it's fixed or not. I'll try to post again when I can put some more miles on it.
There is a procedure to break-in the valve bodies that supposedly fixes many of the harsh shifting concerns that people have, but good luck with getting a dealer to acknowledge the issue and apply the fix. I've been to two different dealers so far and received the same treatment as you. So far there's been zero improvement because all they do is reset the adaptive shift tables (which is easily done with Forscan).
