Brother, they're all good, but don't you want to make a version without effects? When I've made a game, there are cases where it's better for me to attach effects.
Hi, separating the FX and noFX pngs and organizing then in different folder doubles the work when preparing the asset for releasing and can delay it if I do for every move. But knowing that I also let the aseprite file available, where it's possible to personalize the sprites and exports then in the way that works better for you.
