It seems that cua-indent-rectangle always uses tabs.
Kim, can you comment on this?

(defun cua-indent-rectangle (column)
  "Indent rectangle to next tab stop.
With prefix arg, indent to that column."
  (interactive "P")
  (if (null column)
      (cua-insert-char-rectangle ?\t)    ;   <-------
    (cua--indent-rectangle nil (prefix-numeric-value column))))
