I'll be using wood for the soffits and fascias. I'm planning to give
them primer, undercoat two times and gloss coat three times, all done

done once everything's been nailed on.

With this much paint, I doubt the wood will be in any condition to
breathe.

you need to put primer on the nails before the final touch up. The
reverse side of the wood can be left bare or with a microporus stain
so that the wood can breath.
