Good to have you two aboard, and I’m hoping we can be of some help to you in your new venture. I use a standard refrigerator (very used, discarded by someone else, and free) along with a thermostat, which is essential. As to the insulation value of a glass door, it might be helpful to look at the energy rating of the particular unit you’re interested in. Certainly it can’t be as efficient as a thicker, insulated door; but it may not make a tremendous difference. Esthethically, the joy of seeing your creations every time you enter the kitchen might be worth the loss of a few cents a month in energy savings. I can’t testify for everyone else; but I don’t make cheese because its cheaper - it’s NOT! - I make cheese because I enjoy it and it’s better. So, indulge yourselves and make it as much pleasure as possible.
