New compost bed, what to grow?

I build raised beds from pallets, fill them with leaves, and cap them with compost.
It's the first year I've used leaves at the community garden, previously I've used woodchips there, but we are low on wood chips and I had extra leaves.

Because I can't be at the  community  garden everyday, I have buried 5 gallon buckets full of woodchips in each pallet raised bed.
They act as water reservoirs, while the bed still has access to the surrounding soil, for what it's worth.
Each bucket has woodchips inside, a fill tube and holes through their sides(about half way up).
I then pack more wood chips all around buckets and top everything with compost.
This time I've packed leaves around the outside of the buckets, instead of wood chips, and I anticipate they will decay faster than the wood chips inside the buckets, but I think things will work out.

Since it's basically a compost pile, any added production an extra bonus, but it's ~16 square feet of growing space,so I don't want to waste it.
I can think of dozens of things to plant in this bed, but I'm eager to hear suggestions from my cohorts here😁
