I have to preface this by saying I am NOT an instructor and in 25 years of golf I could count on my hands the number of lessons I've taken. Quick background, I'm a lefty and came from baseball, I swing hard and until 5 or so years ago my swing was very long (back and shoulders). My first lesson ever was about a year after I started playing and I had the same experience you describe. I was trying to figure out putting the clubface on the ball and the pro was talking about "feels" that were WAY beyond my knowledge. I had a 3 lesson package with him given to me as a gift, I never went back for the last two...
Fast forward 20 years and I play sporadically, some years 50 rounds, some years 5 (kids, job, blah blah blah...) but I can hold my own against my buddies on our annual trip. Typically in the low 80s. I'd been a solid 10 index since 2002, no matter how much I played or practiced, it just was my game. I was beating balls on the range in late 2019 preparing for the annual trip and the pro at my home course, who is a family friend, wanders over and starts chatting. In 5 minutes of looking and one video taken he changed my thought process and my game. I'm now a 5.9 and trending down at 46 years old with the same job and same kids and wife 🙂
All of this is a long way of saying that finding a pro who speaks your language is the most critical part of the process. If you are 6 months into the game and lack the understanding of proper grip, setup/alignment and rotation, every single item you listed is worthless to you. Find a better pro who will teach you the fundamentals, find out if any local courses host "range time with the pro" group lessons or something similar. "Golf with Aimee" is, in my view, a great YouTube channel where she explains concepts in language anyone can understand. Don't give up on the game, the frustration only increases the reward when you pure one!
