Have you bled the master too? Run a litre of fluid through each caliper. It will go. Bleeding sequence doens't matter.

ABS bleed doesn't do much IMO. If you have a poor pedal, just keep bleeding. Also nope, you want fluid to get by. If you can't get fluid out the caliper you have an ABS issue, but you don't.

Master cylinder is the only thing left. Booster doesn't affect it. You're trying to move an incompressible fluid, so if it compresses, there is air or the fluid is passing the seals in the master.

You don't need to bin the fluid btw. Just reuse it.

Unlikely, but could be dead out the box. If the seals were bad it would pass even with the engine off though. IMO it's just air. You could take your old ABS pump and fit bleed nipples onto the outlets, bleed it through and prove the master. Bit of work though.

Bleed the master. Sequence doesn't matter. Bled mine last weekend, had it sat empty for 2 years. Bled in whatever sequence I wanted, just walked round it. No issues with pedal.

*no VCDS used either.
