Anyways; useMemo in your example will not help at all; the fiber that holds the component will only rerender when its props changes, same as useMemo. An example where it would actually help: if you had a callback that had to be created dynamically inside your component or whatever you used inside there was computation-heavy.
Also, for ajax requests, you need no redux nor thunks. The second last example of my post shows how to do it in an effect.
