I'm not sure the thickeness of the rails but the legs are like 1 5/8 thick
. The rails are bigger than 3/4 for sure though. I'm afraid of cutting into
my tenon on my rails.

From your descriptions thus far:

A 1/4" dadoe is quite sufficient for a plywood panel that is framed by
rails and stiles/legs.

I concur, FWIW.
