No.  `split-window' is low-level.  But you're right in the sense that
calls to it should be replaced by `switch-to-buffer' wherever possible.

Conceptually yes.  IIRC some of the buffer switching functions were in
files.el only until recently.  So the presence of window handling
function in the File menu is probably historically motivated.  But menus
are (also) for people who might not even know what buffers, windows or
frames are.  Most of them know what files are.

Doesn't the buffer menu get crowded when there are lots of live buffers?
I can't tell because I have (global-set-key [menu-bar buffer] nil) in my
.emacs for years.
