Maybe things that need extra-sharp drainage to survive a cool wet winter would do well in the top-layer of a multi-tier, very raised bed.
A friend had a small very-raised bed with tiers, structured like a wedding cake, with layers of concentric circles, each layer smaller than the one below it.
Like a raised-bed-on-top-of-a-raised bed. Then another layer on top of that.
The top-most layer is well-drained unless climate change brings us monsoons instead of drizzle.
