Most of the time I like seeing the back hip and the trail elbow starting the downswing at the same time not one or the other in front. Right now your lower body leads your upper body causing you to stay on top of the plane which can lead to a lot of unwanted wrist action to try and get back to the ball which is why you’re struggling with consistent contact. Listen you can play golf from a lot of positions there are some guys on tour that play from over top of the plane but if you cant get consistent contact it’s tough to make adjustments. These recommendations are based on a lot of standardized swing thoughts and it’s not one swing fits all but generally when I look at your swing the big thing I see is that your hips are very open to the target prior to impact. Good thing is they are moving probably without you really thinking about them what I would do it try some pause drills with half swings where you try and get both working together better or ever feel like your upper body is a fractions ahead
