Correct, those fish are what I refer to as forest fish, they occur in forest streams that are generally slower rather than faster current, and for half the year the forest floods and there is little or no "current".
One comment on the fish, I would not recommend Betta with other fish like tetra. I consider Betta to be worth their own space. And if females, a group works better.
What is your light? You mentioned bright, so I ask.
Larger swords need a deeper substrate, but you can achieve this by terracing the substrate. Push some of the substrate from the front towards the rear; as it is unlikely to stay like that, some inert rock or even wood to make small terraces (steps) works well. The the larger swords would be planted at the back in the deeper substrate.
Front cover would be good with the pygmy chain sword, it only needs 1-2 inches of depth.
Most plants need fertilizing because there is unlikely to be sufficient nutrients in the tap water, fish food, and organics. Substrate-rooted plants tend to be higher nutrient plants. A good liquid fertilizer is sufficient, I recommend Flourish Comprehensive Supplement for the Planted Aquarium. I believe it is the best complete preparation. Nutrafin's Plant-Gro liquid also seems to work, though it takes more of it. Flourish uses very little, in a 33g 1/2 a teaspoon once or twice a week is sufficient, so long-term it is less expensive.
