Your insight is more or less correct. Overall you seem to lack a sense of tightness in all of your movement.
On the press, aim for your nose on the way up and on the way down. You will likely move your face out of the way, if you don't we tend to only make that mistake once.
Squat: Not bad, decent job with the knees, but again, you're lacking tightness overall.
Deadlift: Same.
You stated you did strong lifts a few years ago, and changed to SS half way through and that this took about a year. I'm not sure you properly did the program given you size/height/weight.
I would recommend a complete reset...start the SS program, EAT, drink your milk, and get tight for ever lift. LP work for some time for you.
