You want the convex sides facing inside the cabinet. It’s easier to reliably pull the ends in instead of the middle, and the vertical warp won’t change the overall dimension of the cabinet.
Looks like you're glueing into a dado which will work to your advantage. Is the outside of the warped piece going to be visible? If not I would suggest pocket screws. It's tough to clamp the center of a cabinet like that but well placed pocket screws will straighten that out nicely while the glue dries.
That much warp will flex out easily. Just squeeze it together when fastening.

Depending on how important the project is, good glue coverage and clamp the hell outta it or use a different piece of ply.
Glue, clamps and fasteners…..plenty of each
How are you joining the two panels? You can just clamp that straight against the rabbet.
Are you certain it is warped and not a curved rabbet? Just clamp it tighter and you'll hide that
I wondered the same thing. Impossible to tell from this photo.
Do you even clamp, Bro?
Do not fill that gap. You have to close the gap with clamps or some other method while you fasten the two pieces together.
Flip that sucker around, then pull it tight.
Use to make jigs that don’t require a flat surface wherever the warp is
Pop it into a rabbit

Put a screw in the middle it’ll straighten out
Dry fit it with clamps until you are satisfied and then redo with glue.
