Perhaps -- it depends on how things a layed out.  E.g if I have
text and image (IIII) like this:

  abc      IIII
  defgh    IIII
  jkl      IIII

and cursor is on `f' I would probably prefer if C-e moved cursor to
the position after the 'h' rather than to the right edge of the
IIIImage.

C-x o (and C-x 4 f etc) should ignore anonymous windows.

I think most of the relevant commands use a small number of
functions to select the target window -- we only need to
fix those functions, not each command.

Sure, it need to be thought about before implementing anything.

In a block model used for WP, there are probably lots of similar
problems that we would have to solve.  I don't think that can
be avoided no matter which approach we choose.
