Deck beams – 4×8 ACQ HemFir or built up?
My brother is building a deck in Alaska that requires main beams to size at 4 x 8. He can get 4 x 8 HemFir (no SYP in AK!) or can build up from standard 2 x 8’s w/ PT plywood between.
My inclination is the latter due to the tendency of the 4 x 8s to check and twist –

I'd probably use the built up beams too, for the same reason. And although the 2X8s will twist, once you put them into the sandwich, its likely that the assembly will hold straight.
Politics is the antithesis of problem solving.
