OP, re: your knee/hip flexion coordination on descent--
It’s better in the original video. The problem there was not that your knees were forward. It was that they were sliding forward at the bottom, which is an error caused by not staying tight, i.e., not maintaining the active hip, at the bottom. Don’t know whether anyone made this distinction clear to you when you posted that first video, but given your response to it, I’m thinking not.
As for your lumbar, yeah, veryhrm is right--shove your knees out a little further and focus on staying tight. It actually helps me more to think in terms of actively pulling my knees further apart then to think about shoving them out, so maybe that will work better as a cue for you, too.
And actual weightlifting shoes will probably help.
