Amazon sword (Echinodorus amazonicus) is a good background choice.
This is in my 110G, ~20" from the substrate to the surface - the filter outflow pushes the amazon sword towards the front of the tank, but they graze the surface (you can see one of the leaves on the left doing it).
The tall reddish-brown plant on the right is a Dwarf Lily (Nymphaea Stellata)
Note these are both in my high-light, CO2, EI dosing tank -- but I think you'll see the same kind of results even without it.
The foreground plant is Sagittaria subulata - grows fine even in the mostly-shade areas of my tank.
