Tuna, regarding the hips, here's a couple of things that have helped me.
First, for hip height, it was learning to think of driving my hips up for the movement that greatly helped me. It's similar in effect to the "push the floor away" cue, but for me thinking of shoving the hips up has helped cut out trying to straighten up my torso to vertical too soon. Thinking of it as what the kids call twerking, "point your bunghole at the back wall", and so on are similar. Thinking of the old-time strongman feat where they'd wedge themselves under a flat, wooden platform with several pretty ladies sitting on it, and lifting it by pushing up with their hips - that's the kind of idea.
A second one that's helped me has been lowering the point of visual focus at the beginning. For me, looking down closer to the ground helps, again with not getting a vertical torso in setup too soon. If you keep a neutral neck throughout the deadlift, your natural point of aim for your gaze will change significantly - starting by looking where you end cranks the neck up at the start, and I find that makes it harder for me to do what I should with the rest of the body. In your most recent video, I'd be looking about where that other barbell is in front of you, maybe even closer.
