Some low light and hardy freshwater plants that involve little to no maintenance are java fern, any species of anubias, water sprite, subwassertang, and marimo moss balls.
To further reduce maintenance you could consider adding 2-3 amano shrimp and 2 horned nerite snails to your stocking plans. They will take care of algae and biofilm on the plants and walls of the tank. They are also incapable of reproducing in freshwater, so you wouldn't have to worry about them multiplying and adding to the tank's bioload. These species will do well with a group of small schooling fish, such as chili rasbora, ember tetras, or celestial pearl danios.
I would also suggest to focus your filtration around biological media, as it is most effective at reducing maintenance. I am a big fan of marinepure media and use it in all of my tanks.
