I don't think that a carbon fiber frame, at least as done for eBikes especially the Bafang specific ones, means you are getting "light weight".
@greeno here has an aluminum frame 25ah battery M620 motor FS bike that weighs less than my carbon fiber Luna Z1 with the same motor and a 17.5ah battery.
If I am reading your needs correctly you would be happy with an FS M620 bike. High power, mid drive with torque assist and throttle able. Fast and fun on any type of road but also able to crush single track, although you say you don't need that feature, until you experience it that is
Cost is usually more reasonable than big name brands that have EU spec 250w motors so beloved by some on this forum.
There is a thread on here about 2022 Bafang models that you might want to read if you haven't already. Frey seems to pop up alot in that thread, the AM1000V6 is particularly appealing, but anything you decide on will be months out for delivery. None of the bikes you list are available to purchase any sooner.
