Proofing bread and storing cigars are two entirely different things - you're at a higher temperature and the dough has more water in it than a cigar. Also, some stand up freezers just have coils in the cooled space, unlike refrigerators, they aren't using an evap and a fan in a separate compartment. That fan and evap setup are going to dehumidify the air when the compressor runs, this condensate is then drained to a pan under the refrigerator to evaporate naturally.
Now, if you want to use a stand up freezer that is totally sealed, that will hold humidity quite well. As will an old refrigerator where there is no fan, just a cooling grid around the ice box area. But a modern refrigerator will not.
