Totally agree with all your points. I also have a rating little over 2000 USCF. New players tend to over-emphasize on openings. To this day I know only names of about 5 openings. I do not know more than a few moves in them. I have generic replies for most of them.
Majority of the games of new players are decided by some stupid blunder. Blitz games do not help improve this area much. Like you said game reviews and puzzles are best.
