What is "average to below average" lighting? The hood that came with the tank with a single 'normal' fluorescent bulb? Or something else?
The three lowest-light plants there are, are Java moss, Java fern, and Anubias. The latter is distinctly more expensive than the first two but also more "feature plant" looking, as opposed to "miscellaneous green messy stuff". All three of those are pretty darn hardy. If you can't grow them, you need to go to plastic plants LOL
Cryptocorynes are also often reasonably low-light, but many are MUCh pickier about water chemistry, substrate, astrological sign, correct voodoo rituals, etcetera. If you find some cheap healthy-looking ones you can try them, but I would not place bets one way or the other.
One smart thing to do if your light hood is "rather inadequate" for the plants' happiness is to not grow the plants on the "floor" of the aquarium, but rather have them partway up the tank. With Anubias, which has to be potted, this means having it up on something and can be rather difficult to make look nondorky; but java moss and java fern are quite happy to be tied to the mid to upper reaches of a piece of aquarium-type wood/root using some monofil fishing line, and they will get more light there and hopefully be happy enough to attach further growth to the wood on their own.
Good luck, have fun,
