Around here, 5x5 Finnish birch comes off the pile in 3/4" sheets.

Same here, although it's actually just enough below 3/4" that it fits
a 3/4" dado just nicely, merely needing the edge broken. Another reson

I don't use cheap ply much, certainly not for making cabinets out of.
Repeatable results like this are just one reason. The only ply I've
used lately has been some cheap Chinese stuff (sorry) for dy-lining
the refurbed workshop, and the thickness of that wasn't even
consistent from one end of the board to the other.
