For the record, my comment was strictly "focussed" on DOF which the OP himself recognized as important in close focus work if one wants to avoid the need for focus stacking.

I certainly agree, however, that even though increased DOF would not be reason to go to the longer focal length for close focus work, there are several other compelling reasons to do so.

I agree with the OP that first among these benefits would be the longer working distance  with the longer FL which can be critical for shooting live objects but also helps avoid casting shadows on the subject.

The longer focal length also provides a narrower field of view behind the subject so that small shifts in camera angle can allow for more selective choice of background field of view and the increased shooting distance alters perspective to compress the apparent depth of the background.

The increased lens pupil resulting from using the longer focal length at a given fstop does increase background blurring which, as you point out, is accentuated further by the increased magnification of the background.
