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.

Huh? The supporting wall is the 4' dimension, the overhang per OP is "12
to 16 inches."

Still too much for two thicknesses of plywood. A few years ago, when faced
with a similar situation, I glued up the countertop from two layers of 3/4"
MDF, leaving several 3/4" wide gaps in the lower layer -- and fastened 3/4"
square steel tubes in the gaps.
