I found a tiny plains island well off the coast, ocean on every side.

Can you grow ALL crops on a plains farm, or just flax and barley?

just flax and Barley. I COULD grow the island to a meadow area (no land, but sailing through it reads meadows) nearby, but it would take thousands of rock. I'm mostly eating serpent stew, lox meat pies, and bread, (having finally stockpiled a couple hundred of each) with occasional sausages, wolf jerky, and eye scream when I'm going to be farming, sailing, or chopping wood in the meadows, so I do not miss the lack of the root vegi's. Easy enough to build a cliff-walled farm in the meadows and a portal to it if I ever decide to farm them.

And I don't know the answers to your other questions. I imagine the trench would be similar, but the island base I'm on keeps any foes from spawning at all, so trenches and walls are meaningless for that base.
