One thing I do If I cut any plywood with a circular saw is to buy a new
plywood blade for each project. I want that cut to be glass smooth. A
simple, steel plywood blade does a good job. They just don't last that
long. The split second it starts to dull, off it comes and gets replaced by
a new/newly sharpened blade.

About how long is that? Say, if you were cutting 4x8 sheets of 3/4 ply
into eight 1 foot by 4 foot pieces for some reason, how many sheets do
you think you could cut with one blade?
