I am also with the keeping water mint in a basket! Mine is in a basket and twice a year I trim it (and the roots / runners that take over that quarter of the pond. It does smell good and the frogs are always hiding in it so they must be keen. Oh and when it flowers the bees love it!
To add some height I have Typha minima - dwarf bulrush, it only seems to be going up rather than out so doesn't take much space up but you often see finches clinging onto it dipping for water or waiting for the bird feeder nearby. You'll find the frogs here too. In the winter I leave the brown leafs (?) Uncut so the area doesn't feel bare.
Because my pond hasn't much edge (its a preformed deep ornamental) I have floating baskets to create some shade; in them I have a carnivorous pitcher bog plant and a Fibre optic ever green grass (can't remember the proper name) that wander around the pond in the breeze. I can't say what good the pitcher plant does for wildlife but you get lots of dragonflies using the ever green as a landing pad.
I do have a dwarf lilly but it only appears late in the season (May) and disappears long before the warm autumn days are over so I think my floating plants do more of the shading work! This could be because my pond is on the deep side and it takes a while for it to warm up. I might raise it on bricks this year to see if that helps if I can brave getting in the cold water with my snorkel.
In the final edge I have purple and yellow iris: they add some amazingly striking colours to the pond which is more for my pleasure but the bees show interest.
My hornwart seems bomb proof (I have fish that seem to think it a delicacy) and is where you'll find the frogs come mating time.
I hpe that helps
