Do thermal pads or thermal foam make any discernible difference in operating temperature with M.2 SSDs?

Only if there is a heatsink on the other side of that thermal pad or foam. One side contacting the SSD chips; the other side being the heatsink or cooler.

What about when the drive is in a laptop that has a metal bottom case or if the drive is in a metal external enclosure, in which case does the thermal foam in fact draw heat away from the controller using the metal as a heatspreader? I'm curious to if this does in fact work or if it's one of those things that makes sense on paper but doesn't make any discernible difference in application.

The thermal pad has to physically touch something else, preferably metal.

Yes, metal in a chassis or even a metal outside case can act as a heatsink.
