Emacs-lisp hooks for detecting change of active buffer?

I am trying to execute when the active buffer has changed by either

1. Changing the buffer in the current window (e.g. C-x <left>).
2. Switching to another window (C-x o).
3. Switching to another frame.

Are their hooks suitable for detecting this?

What I figured out so far

Looking through the Standard Hooks I found the following options, none of which quite do what I want:

• buffer-list-update-hook is called for both (1) and (2). It is however unsuitable, because it is run before the buffer is changed, while I want to know what the current-buffer after the change is.

• window-configuration-change-hook can be used to detect a change of the buffer displayed in the current window, and it is run after the change, as needed. It is however not run for M-x other-window.

• mouse-leave-buffer-hook seems viable for detecting mouse-based window switching, but it gets called a bit often (for me four times upon switching windows with the mouse, three times before and once after switching), which requires additional logical to prevent multiple execution.

• post-command-hook would be viable but a bit heavy handed, risking significant slow-down of the editor by even minor bugs.

• Since my action would need to use with-selected-window, which triggers these hooks, care has to be taken to avoid endless loops where the hook triggers itself.
