Hey friend! I do know that and I have a bunch of them already, all those floating plants are soil-less. And some of those floaters are substantial plants too. This stuff called water lettuce is sizeable and so is this stuff called 'water hyacinth'. Now I grew hyacinth in the garden before and I doubt the two are even closely related...
So yes, there are many water plants that grow well without soil, however there are countless more that won't do well without soil, unless you are talking about hydro-ponics. Now if that's the case, fish won't be able to survive in that too rich of nutrients in the water.
For example: Those four Lilly pad plants-tubers, those plants are considered heavy feeders and more than likely they will LOVE that soil that I prepped. I have quite a variety of plants already and they are all floating in that spare 20 gallon long 'quarantine' tank.
Hey NU_FTW, thanks for showing interest in my hobby! I get the impression you did a lot of fish tanks in your life!
Here's a few pics:

And then I put all three in the tank. I decided with the 4th Lilly that I will grow it on the deck just in it's own container. I read that it is very popular in Asia to grow lillies that way. I have more tank talk but I will make another post for it. It's some heavy shit! I say I say!
