I disassembled the hub only as far as you did in your second video. The only cone I had to remove and install was the non-drive side cone. I first assembled the hub with it adjusted just to the point where there was zero play. I found the freewheeling drag. I removed the wheel and readjusted the cone so there was play (I could feel the side to side knock once the wheel was installed), and the freewheel drag was still there. The hub shifts fine while on the stand, it rear wheel rotates forward fine and smooth. It's just the backward rotation where the drag is very noticeable. On the stand, I rotated the cranks, let go, and the rear wheel drives the entire drive train including the cranks forward. I can only think a drive side dust cap is making contact with the cog.
The hub is definitely assembled properly. I double checked it with the exact Shimano Tech doc for the SG-8R36, all dust caps, driver cap, and snap ring are installed correctly in the correct order.
