So, any thoughts on whether it's okay to use plywood for more
strength or would I be better off using particle board?

You are better off using plywood, one thickness or two. Since there is a
considerable overhang, be sure it is *very* firmly attached to the
divider.

think corbels. there's no way 2 thicknesses of ply 4' wide will be sturdy
enough not to flex enough to cause problems.
