That's fine. I feel the same for squats: better mobility and the feeling of being "locked to the ground" - but that doesn't mean they're the best option for deadlifting.
This is going to sound pretty dickish, because you have a pretty good attitude, but please just pause for a moment and consider the irony of starting a thread titled "beginner deadlift form check" and pushing back against advice from two guys with 550+ deadlifts (flipcollar is over 600, I'm pretty sure) by saying "Nah, I don't think it's the shoes, anything else you guys would comment on?"
To be honest, I think form videos shot with less than about 80% are of limited value anyway, so it's hard to tell if you're actually pitched forward on a heavy pull, but just know that most experienced lifters would recommend the same thing. Weightlifting shoes with a raised heel are not meant for deadlifting; they're for squatting (or more directly, for Olympic weightlifting, where getting from an extended-vertical position into a deep front-squat or overhead-squat position in half a second is a necessity of the sport). I know that the allure of the "locked to the floor" feeling is strong and I love it for squats, but you can feel even MORE locked to the floor pulling in bare feet or socks, IMO.
I'd say that for one, you should try pulling in just socks for a few workouts, and for two, you should shoot another form-check video pulling closer to your 1RM. If you don't really know your 1RM, then shoot us a video of a weight that's hard to pull for more than 3 reps.
