Small wine fridge sounds good, as I believe those can be set to a little higher temperature. We have very little option but to refrigerate this time of year, certain nights anyway, as we hit stretches of 90 degrees and sometimes 80% humidity. We keep stock in the projection room, downstairs stock in the kitchen fridge & "samples" (usually melted in the bags) on the rack, running back and forth to the fridge when somebody wants something. I see some large "chocolate fridges" actually exist, probably for production, and they talk about being able to vary the humidity up to 70%, so now I'm not sure if chocolate likes humidity or not. But that's one thing we have, in spades.

Well, I've heard this from a Belgian chocolatier quite a while back already. He also explained me how to keep the glossy surface of chocolate when you're working with it, which isn't particularly easy. I'm pretty sure I would fail at a repeat trial.
The optimum long-term storage conditions for chocolate seem to be somewhere just below average room temperature. That would be something like ~70 °F / ~20 °C. Chocolate definitely doesn't like too much humidity, because moisture around the chocolate will eventually dissolve the sugar in the outer edges of the chocolate and will cause sugar bloom.
I did a quick Google and according to this site, which seems to confirm most of what I said, the optimum relative humidity is below 50%, but real trouble apparently only starts around 78%.
Storing chocolate at cold temperature seemingly isn't really a problem, only if you move it back to a warmer environment, you need to do so in a dry environment or risk it turning grey. This can also happen to chocolate in air tight packaging, because of the moisture inside the packaging condensing, so a dry environment will not even help you there. But if you sell it refrigerated, it will be consumed directly afterwards, so no problems there.
