Mounting tv to metal stud that have plywood in them

I have a condo where I am mounting a tv to the wall, I know I have metal studs and toggle mounts are an easy solution, but I recently discovered that one side of the mount that I would be mounting on actually has some plywood in the “c” opening…

can I do a hybrid set up with toggle bolts on one side and regular wood hardware on the other? Any recommendations?
