Help deciding on plants for container pond

[ChefConfit]

So I recently purchased a large plastic barrel planter to turn into a patio pond. 

I'm planing on making a shelf and getting some of the fabric pond planting pots in order to add some bog/marginal plants, but I've never had any pond plants and could use suggestions. 

I know I want verigated water celery. I would also like something tall such as a grass or Reed and something that will trail out and hang down over the side of the container. 

I was thinking either sweet flag, blue-eyed grass or dwarf cattails for some thing tall. For the trailing plant I'm at a loss. Can pothos be grown as a marginal plant? 

I was also wondering if I should go with an aquarium lily/tiger lotus or if I should get a smaller variety of pond lily.

I've also got dwarf water lettuce and Frogbit to use as floating plants. As for submerged plants I'll probably just do a mix of everything I've got in my tanks and see what does well. 

Here's a Pic of the container. Somewhere between 23 and 24 gallons, so I figure after adding substrate and planters I'll have about 20 gallons of water for fish. 

The pond planters I'm looking at are 7in cubes if that's important.

I’d like to hear from @Streetwise who has some very beautiful smaller ponds. He seems to have good success with plants and fish. We used a 15-gal half-barrel like what you’ve got. All of the plants from inside tanks we tried died. Maybe too much sunlight, I think... or not enough fertilizers... not sure. Only water lettuce thrived. And it got really epic-huge!

Sweet YouTube channel dude, I just checked out some of your other videos too, your platy fish look great, I've always wanted a big colony of red wags.

Thanks! Just submitted BAP Mollys— should earn “Advanced Breeder” award at fish club. Not a Master Breeder yet, but 2/3rds of the way there.
