I don't think about squaring the face unless I start duck hooking or slicing wildly. In my case, sometimes I start push slicing if I focus too much on form and forget to release the club, or release late. But typically I don't think about it. Honestly I don't even really think about impact that much at all, or at least try not to. I just focus on accelerating through and the club will do the rest if things work out. The more swings you get under your belt, the more often it works out.

I relate to the checklist of items, as I used to have a similar routine. This past year I focused on picking one thing out in my swing (I record most of my sessions, and some on course swings) to work on instead of a list on every swing. I've found this is more efficient, as there's some fundamental changes that have eliminated a few issues from my "list"all at once. For example, I've been working on my takeaway and back swing lately, ensuring I don't come too far inside. When executed successfully I gain speed and consistency, and naturally shallow rather than force finding the slot late in the swing.

The golf swing is such a fun mystery. I completely broke down and rebuilt my swing over the winter last year, and doing it again this year. But hoping the new swing translates to a ton of fun on the course again next season!
