Here’s where I’m at now…
FC 8
CC zero or close to it
pH 7.3
TA 120
CC 150
CYA 60
How am I doing? My pH has been inching down. Was about 7.8 a week ago. Should I be adding some Borax or Soda Ash at this point or leave it alone? In general do you wait for pH to get OUT of range, say 7.1 or 7.9 to do something about it, or do you proactively try to nudge it back toward 7.4-7.6 when it drifts anywhere above or below?
All I’ve been doing is periodically checking and making sure FC is up in range and adding liquid chlorine every couple days or so to maintain. Got CYA from 90 to 60 doing a bunch of partial water drain and refills over the course of a week or so.

And you're not using anything acidic in the pool like chlorine tablets? Have you been adding water lately? If so, have you tested the pH of that fill water? Perhaps it's very low and that's why. If the pH hits 7.2, you might look into creating some aeration. Any bubbles generated in the water like that will help increase the pH but eave the TA alone.
