If it were me I would do either option 1 or 3.
Celestial Pearl Danios are fin nippers, and shouldn't be kept with Gourami. The long, delicate feelers of Gourami are especially vulnerable to attack from fin nippers, and once those are damaged they won't grow back and the Gourami will be missing one of its main ways of interacting with their environment. So I would remove the options with Celestial Pearl Danios.
Cardinal Tetras require a pH of 6.5 or lower and soft water to thrive long term. You might want to test your pH and hardness levels and see if they fall within the range of Cardinal Tetras or not, and that can also narrow down options some more. I've found that it is cheaper and easier to keep fish that can tolerate the water you already have.
Neon Tetras usually don't fin nip, but may when kept in smaller schools. So for option 3 I would have the Neons be the larger school to make sure they behave themselves and get 8 of them, and just 6 of the Chili Rasboras.
