Planning a shop build, any suggestions?

the trusses of a pole barn are usually 4’ on center, with some of the higher end barns at 8’ on center. That’s a mighty big span for insulating the ceiling.
Yeah walls will be insulated with closed cell foam, not positive on roof yet. Probably spray foam on underside of roof with no ceiling. If I install a ceiling, I could insulate the ceiling and have a “traditional” attic. Leaning toward insulating the roof line though.
