Car is back from the dealership. No codes tripped. Ford told them to re-flash the engine and transmission ECUs.

After getting it back, it is possible to free rev the engine (in Park) and get it to hold a steady speed, but with great effort. You cannot pick an rpm and just rev it at that rpm. Dealer said this is normal on eco-boost engines.

The loaner vehicle was a 2020 Escape with a 1.5 Ltr Eco-boost inline 3 cylinder both direct and multi port injected. I could effortlessly Free rev the engine to any rpm I chose, just like every other engine I ever owned. I traded in a 2016 Escape with a 2.0 Ltr Eco-boost inline 4, but it was only direct injected, same thing.

This 2.0 Ltr Eco-boost inline 4 cylinder both direct and multi port injected is odd.
