When you label something the implicit purpose is that it is now reusable. But an InnerWrapper class defined within a React component should be private and not actually reused, whether you are using global styles or css in JS (because it should be a private implementation detail—otherwise the component consumer has to also figure out the classes to apply).

What makes you think that? I wouldn't use a wrapper element from a different component in another component. At some point you just have to use common sense.
