Hi there EmeraldJones!
There's a lot of opinions being thrown at you here, it must be getting pretty confusing! I'll just add mine to the mix
I have a 60L tank with platies and a lot of live plants. The fish LOVE the live plants and are constantly swimming through them, it makes them much more relaxed and playful. Shrimp will really love live plants and especially some moss which they can hide in and pick clean.
I wouldn't recommend putting platies in a 40L tank as they can grow fairly big. I think your idea of guppies and shrimp would be fine in a 40L. Alternatively you could consider endlers which are smaller so you could keep more of them.
Well done for doing your research!
