In each case there's a reason they aren't (with the exception of blue- and strawberries, birches---and rhubarb, sorta) a major product of commerce or home production for syrup or grown outside a limited area. As for maples, the website below suggests Douglass maple for SE Alaska; maybe it will work for your area too. If I were in the PNW I'd go for raspberry and blackberry syrup instead.
