Welcome to Tropical Fish Keeping forum.
Your mentioned plant selection includes some higher-light plants (Wisteria, dwarf hairgrass possibly) and low light plants (Anubias) with others being moderate light. You can try these together, but expect some issues. It is not easy to accommodate this range in light requirements.
What exactly is the 40w fluorescent tube? This high a wattage in T8 would mean a 48-inch tube, so I'm a bit confused. I would myself not want this over the tank, but stay with the two T5 NO tubes.
As for carbon, I wold not use the liquid supplements. They are toxic to fish, bacteria and plants if overdosed, and even as the recommended dose some plants usually melt. Vallisneria is especially prone to this, and while you don't mention Vall you do mention Sagittaria which is in the same family.
If carbon is needed, CO2 diffusion is the best way. However, this sets up a very different balance level, which you light will not match. I suggest giving the tank a try with no added CO2 for a few months. The dwarf hairgrass is the only mentioned plant that might not manage without CO2.
Planting a tank requires some experimenting to see what will work and what won't; we can't expect all plants to manage together and thrive, just as all fish can't.
And that brings me to the fish. If the Betta is a male, I would not include it in with the others. Neons will likely be eaten [mine were] as they are too colourful for a Betta. Plus the neons have a tendency to nip Betta fins. Hatchetfish and Betta is also not a good match, for the sake of the hatchets. And corys are shoaling fish than must be in a group, no less than five, but more is always better; they can be the same species, of mixed; but it is best to have at least 3 per species if you go with more than one species.
You can check out these fish in our profiles, second heading from the left in the blue bar across the top.
And last, with live plants, you do not need to "cycle." I would not add any artificial ammonia. Do some good water changes to get rid of this, then add the first few fish if the plants are settled.
