I made some raised garden beds with green-treated lumber a few years ago
(the new green stuff, not the good old arsenic kind.) I had read that
you have to use hot-dipped galvanized nails, or the salts in the wood
would rust the nails completely in two in a short time. I used 16d
bright common nails, not galvanized at all. I knocked one of the beds
apart this spring, and the nails were rusty but still strong and
holding. Maybe the problem is just with flash-galvanized nails?

If you want a wood that's just naturally decay resistant, cypress is
about the best there is -- assuming you can find cypress lumber.
