But, as of a few weeks ago, I have DROs on the lathe and mill, so
digital maybe makes more sense.

The lathe uses output from a micrometer?

I'm going to make a measurement with the micrometer, find the
difference from the desired measurement, and then move the tool some
number of tenths of a mm, say to take up half the difference and leave
enough for a finishing pass.

Is that what the data output on some micrometers is for?
