The function ultimately used by both is 'set-window-buffer'.  One basic
feature of 'switch-to-buffer' not shared by 'display-buffer-same-window'
is 'switch-to-buffer-preserve-window-point'.  And obviously
'switch-to-buffer-obey-display-actions' gives the user the opportunity
to override the behavior of 'switch-to-buffer' in an arbitrary way while
'display-buffer-reuse-window' per se cannot be overridden.  OTOH the
behavior of the latter can be controlled via alist entries.

I think that the most important improvement of "category" should be to
override "lru".  It might also help with 'image-dired' for Bug#74246.

And there should be a convention for setting it up maybe with the help
of some sort of sub-categories.  IIUC 'comint', 'xref' and 'image' might
not be distinctive enough for all purposes.  I cannot suggest much here
because I do not use either of these.
