Typically I find, right after a brake flush, you need to start the car and press on the brakes and top off fluid prior, during, and after.

Assuming you went furthest from master cylinder to front, everything you did sounds correct however, the output of your effort points to air in the system.

Since the air/gas is MORE compressible than the fluid, it would make sense that you can eventually build up pressure.

There COULD be some other issue causing your symptom like a leaking master cylinder. The caliper you replaced could also still have air in it since it was new.
Also, OP, you can manually activate the ABS to try to pump some of the air out and then re-bleed. Just find an empty parking lot, accelerate, jam on the brakes like you're Mr. Brembo and viola', ABS activation. For even easier activation, do this while turning.

Possibly tap the new caliper with rubber mallet as bleeding. Did this during st40 install.

Yes! Another good tip. Break the surface tension of the air bubble(s) and the caliper.

I think activating the ABS is the key...working on the software install. I'll let you know how it turns out.
