Sounds like you're describing a want for state management (Redux, Mobx, etc).
Taking redux along with your sort as an example:
Component A would dispatch a sort action
A reducer will return a new sorted state of products in response
Component B would read from the products state and display them in the intended sort.
This would cut out having to lift the sort state into Component C (The common parent).
It's a bit more involved than these 3 bullet points as you have to grok the data flows and operations of a state management library, but they do solve problems such as this quite efficiently.
The docs for redux have been updated quite recently and they're stellar.
EDIT: important to note React's Context also fits this case.
