6M yurt = perfect nomad yurt imo.
The simplest floor is tarp on ground covered with circular carpet. Erect yurt on carpet. Fold tarp up under yurt cover outside the wall and secure with the low rope or band. Voila! a bathtub floor and no drafts and bugs. Cheap as it gets. Easy to install. Dry. For nomadic this would be my 1st choice. Lay a sheet of cement board under the wood stove. You need a tight fitting cap or a bonafide
to keep water out.
Alternative wood floors require real work/money.
SIP panels by a pro $$$$
3/4 t@g OSB screwed into pressure treated 2x4s 'sleepers' laid flat on the ground, on 2' centers. Cut the whole shebang to yurt diameter. Paint and label the entire system for easy id later when moved. Use new screws each go round.
Second. Two layers of osb screwed to eachother. Lay out the first layer. Orient the second layer at a right angle atop the first. Screw the two layers together. Cut to diameter. Again, paint and label everything. Use new screws each go around. Moving this means real work, but it is portable and relatively cheap. You need a truck or full size cargo van.
Third. Circle of osb atop pallets. Real work. Truck for sure.
IMO the best nomadic system is plastic tarp and carpet. No bugs, no drafts, dry, cheap and easy. Just roll your floor. You like apples? How 'bout them apples? 6 meter roll up rollout in a weekend if the move is close. When the tarp gets funky replace it with another cheap one.
