I'd think beginning of window odious.  I would recommend start of
line, start of section/defun, start of buffer.

As to the implementation: I would recommend to make it stateless: the
implementation will simply check whether the cursor currently is at
the start of line/section and move to the beginning of the smallest
unit for which it is not yet already at the beginning.
