The material you are cutting largely defines the blade you will need to use. If you are cutting laminate flooring you can purchase what’s called a “melamine” blade. These types of blades are designed for composites and non-fibrous material.
If you are only cutting common lumber and occasional trim, the standard blade that came with your miter saw will likely be more than enough to meet your needs.
If you only planned on making a couple dozen laminate flooring cuts, I wouldn’t even recommend buying a blade just for that. Your standard blade will do, and you won’t notice much if any difference between blades for a small number of cuts.
