N6DSW: both of those points are good, and I agree with you. Here’s how I addressed (or mitigated) them:

repeatable squareness: I never just push down on the handle. I always push in on the little protrusion below the handle (the thing that’s flush with the handle when the handle is down) and then lock it. In fact, I usually put the heel of my hand on that protrusion and grab the rail from below with my fingers and then squeeze. This makes locking the fence a two-hand operation, but that’s never been a problem (I can do it with a push stick in my hand). This is so automatic now that I had to run downstairs mid-message to to see what it is I actually do. Basically, this forces the reference points to make solid contact before the clamp gets involved. I get absolutely perfect results every time (best I can tell).

micro-adjust: I got a cheap ($10) dial indicator from harbor freight and mounted it to a little 5-minute fixture that I clamp to the rail. It only gets 1” of travel, of course, but I only ever need it when I want to fine-tune a cut. Make cut, measure cut with calipers, then adjust with the dial indicator. The fence doesn’t slide super smoothly so it’s a couple of bumps back and forth. If I do the trick above as I watch the indicator, then it doesn’t move at all when I lock it down.

I’m not trying to convince you or anything :) If this helps you out, great. If not, tell us how you like the new fence!
