I would think that a drysuit, with fleece underneath, would be most

Absolutely agree, with preference to GoreTex.

However, I'd add an insulation layer under butt and heels as well.
Neoprene or relatively firm foam would be good here, as fleece
isn't the best under your butt. I find it's the butt and heels
that get cold first in cold water.
