I plain old fashioned plywood and leave 'em dry and have never had a
problem. Around here the biggest problem with forms is the hole around
them collapsing and having to destroy the form to get it out.
Exterior/treated plywood might work, but I've not had any problems with
the concrete bonding to the plywood. Of course there will be enough
concrete on it that you won't want to run it through a saw, unless it's
OTOH if the hole is large enough you might be able to rent the steel
forms although it takes some equipment to get them out of the hold.
Course an engine hoist set across 4X4's might do it.
