There are plenty of successful aquaponic setups that don't use a rise and fall bed. Just keep the grow media bed permanetly submerged (constant flood) which will greatly simplify your design and build. So essentially just a second catchment for plants somewhere - could be above, below or beside your fish tank. If you are unsure what pipe sizes to use, over size them and/or use a variable flow pump so you can increase or decrease the water flowrate
The best results would be to place the plant catchment tank outside to get natural sunlight. Connected by input and drainage pipes. Second best would be a skylight or solar tube to get indirect natural sunlight.

This works for some plants, like aglaonema (up to a certain size), spider plant (up to a sertain size) monstera, pothos, etc, but won't work if I want a calathea or a fern or something that has a delicate root system.
My current thing looks like this:
It's just a bunch of green things in an egg crate, but I kinda want it to have a "better design" and have plants that don't really live in water for decorative purposes.

It's not really necesary or possible. Some of the plants I want to have can't survive in "natural sunlight" (like, when they're indoors, you must place them at least 6 feet from the window).
In summer, it will get pissed by dogs and trown trash at and in winter there's snow outside ?.
We have a tiny patch of dirt surrounded by cedars that I've tried to keep plants in. I had to basically clean it daily, otherwise it just looks like a trash pile. I gave up and planted giant hostas, so the trash would not be visible.
