Why would they cool down quicker? Seems to me they would get no cooler
than the flat soil surrounding them. Having gotten warmer during the day,
they should maintain a slight temp advantage through the night, too.

Is there a study somewhere you could point me to?

More exposed surface area? The surface absorbs heat during the day and
flat ground radiates in one direction (up) at night. A raised bed
loses heat up, and from all sides.
