The CFM on the fans is going to be lower if the air flow is restricted with dep.

How is the airflow restricted from the blackout tarp. Wouldnt it be the same rather the gh is covered with clear plastic or blackout tarp? The end walls will be covered with plywood or siding of some sort.

you do a really high roll up vent, you don't need an exhaust for when it's open. If you keep the blackout time short, you don't need an exhaust at all, but it's cool to have a small one to exhaust moisture. A 10" inline will work. A 24" shutter is better. If cost is an issue, i would get horizontal air movement fans first.

The thing about shutter fans in blackout is you need something to block light. Light traps can be pricy.

If you have an auto depp you can just black out for a couple hours at night, open back up, and a couple hours in the morning. U don't get any mold.

I like to keep 3 ft between rows so a wheelbarrow can fit through if necessary ... but I'm only doing 8 outdoors in my 16x30 greenhouse ... finding space for 100 plants in a 20x40 that are already started is going to be a squeeze ... looking good and good luck this season!
