I am making cabinet doors with 1/4" Birch plywood panels grooved into a
Poplar frame.

I was wondering whether I still need to keep the panel floating if it is
plywood since plywood is relatively dimensionally stable and since it
will be aligned with the grain of the Poplar frame along the stiles and
rails.

So is it ok to glue? Or must they float?
(Or is there a middle ground where say I can put a dab of glue along the
mid-section of each of the panel sides)


If you ever want to disassemble the frame for some reason, you would
let the panel float. Otherwise you can glue if you prefer.


Not necessary to glue but prefinish the panels prior to glue up.

Yes.


And as Woodstuff mentioned, spaceballs will solve a lot of your concerns.


The latest Wood Magazine Tip shows cutting small pieces of foam caulk
backer rod to make your own space balls.

Or you can just squirt out a rope of silicone caulking on some wax
paper, let dry, then cut into pieces to get a similar result.
