Question How to combine the single responsibility principle with a finite state machine?

    I'm working on a game where I have some characters to choose from and they each behave differently.
    I followed the Single-Responsibility-Principle and split every behavior like "Crouch", "Jump", "Movement", etc. in separate scripts so that I can attach them to the Player who should be able to do them.
    For example PlayerOne can jump and move but can't crouch. So I attach the "Jump.cs" and "Movement.cs", but not the "Crouch.cs" script.
    So long it's working perfectly fine.

    Now I want to implement a state machine for each player to let them behave different when they are in another state like "InAir-STATE", "OnGround-STATE" or whatever, you get the idea.
    For example when in "InAir-STATE" then "Movement.cs" controls should behave differently than in "OnGround-STATE".

    Example player prefab:

    I read about using enums as a simplified state machine, but don't know how to implement them in a architecture like mine and also that they don't scale well.
    So my question is how to implement a finite state machine (or maybe a better alternative) in a game like this?
