With constant wet feet then lot falls or stands with the light intensity you provide... If it is high tech and high light then it also will be a tad easier on the emersed growth and significantly extends the choices you could make. Emersed plants will definitively favour the extra CO² at their roots and what gasses off from the tank.
Low tech and low light will limit your choices significantly.
Plants that I've personally experienced and seen doing good in relatively low light setups emerged are
Hydrocotyl sp.
Chamaedorea
Syngonium
Cyprus
Spathiphyllum
Most Araceae sp.
Anthurium
Ficus sp.
Philodendron sp.
Bamboo.
But as said, hard to say not knowing the light intensity they will get, it's trial and error. If you do an internet search with the query "Hydroponic plant decor" you will find some more inspirations and sp. of plants that can grow in a pot of water without substrate on the window sill. Aquariums usually are far away from natural light sources then all depends on the artificial light above it.
