That said how many bf of red oak & cedar should I expect to be able to
plane
before needing to replace/flip blades

Depends on how many nails you find.

To extend the life of the blades, try to use as much of the blade as you
can. If you are planing 4" board, don't just keep feeding the center. Once
you flip the blades, buy a backup set to keep on hand. When my blades went,
they went FAST and almost cost me a lot of wood.
