Only DVD-RAM is available in caddy format, tho MO (Magneto Optical) discs are still also available in caddy format, but those are even more expensive.

The other issue with caddy format DVD-RAM media is that very few drives support them, most DVD-RAM supporting drives only support caddy-less discs. Caddy DVD-RAM is an excellent robust rewritable format in my experience.
