This question would probably better fit and get more attention in
emacs-help.  People seem to be quite busy here ATM.

Regarding the question: I would say `window-configuration-change-hook'
or `window-state-change-hook' are the best fitting hooks for the task.
May depend on your use case.

Note that Emacs sometimes internally selects windows temporarily
(`with-selected-window'), so doing something for every window selection
is most of the time not what you want.
