I think you might by right about still having air in the system. I just watched a vid on YouTube where a guy with a GMC that had a pedal like mine. He had to bleed 7 times, cycle the ABS pump maybe 15-20 times until a GIANT bubble came flowing out of the right rear caliper. He finally got his pedal back to factory-new height but he went through a couple of gallons of brake fluid. I don’t mind buying 3-5 gallons of brake fluid if I need to as long as I can get the bubbles outDid you see if that "valve" moves as shown in the video?
If all that checks out, you're left with booster or more bleeding. Some techs I know and trust say to bleed ABS they never bother to actuate the pump but just apply vacuum at each bleeder and pump the pedal.
I dunno, a lot of your symptoms sound to me like you still have air in the system. And I don't think it's a panacea here but I'd tap the calipers with a metal hammer to dislodge any stubborn bubbles. I think you said rubber but I don't see that doing much. But again, I don't think this will magically solve your problem.
You've also got nothing to lose with the gravel approach
