I have the impression that the question is aimed in my direction, but
I don't understand it enough to answer.  E.g. I don't understand what
you mean by "find-file-at-point returns a list of relative
file names" and how it's relevant to the discussion.

Maybe the answer you're looking for is something like:

   (pcase-let ((`(,start . ,_)
                (completion-boundaries <str> <collection> <pred> ""))
               (compls (all-completions <str> <collection> <pred>)))
     (if (zerop start) compls
       (let ((prefix (substring <str> 0 start)))
         (mapcar (lambda (compl) (concat prefix compl)) compls))))
