I've found that adding a bit of crushed coral to the substrate can help stabilize the pH without making it too hard. It's a subtle change, but it's made a difference for my plants.

For a carpeting plant, consider Dwarf Hairgrass. It can adapt to soft water if you provide enough light and CO2. Mine took a while to spread, but now it's covering the entire foreground of my tank.

I found this Aquarium Decoration Rock Fish Tank Natuflake Stone DARK GREY, it says it's 100% natural which sounds good for my tank. It's usually used for cichlids but I think it could work for my Betta. It stabilises pH and hardens the water, so that's a plus.
