If you want a reliable solution for (ii), then use syntax-ppss (e.g. use the
syntax-ppss-toplevel-pos I proposed yesterday).

Beginning-of-defun *does not* conflate the two.  It has always been defined
as the meaning (i).  In just so happens that for performance reasons, people
have used it as a heuristic in syntax-begin-function to get an approximation
of (ii).  If you don't want that approximation, then don't set
syntax-begin-function.
