I have traditional raised beds but in addition have a set of three that I have southernly sloped @15 degrees to boost solar gain.
And no amount of thermal mass can passively boost temperatures above the long term average.
know a grower close to me who grows salad greens all year round in an unheated stand-alone greenhouse with no thermal mass additions on the inside or outside.
I do have a hundred gallon water resevoir in the green house that is used for hydroponics in the summer and a heat sink in the winter with a thermosiphon set up.
Fortunately my area has a 300 day of sunshine average.

Once there was water in them, it was apparent that they did a good job of preventing frost. At which point the size of the settlements made much more sense:
Thus at some point of northern latitude / northern climate, the intensity and hours of available sunshine is simply insufficient to sustain minimum levels of light and minimum overnight temperatures needed for plants to remain productive.
