You may know this, but if not. Pay attention to the temp the unit can hold if that matters to you. There is a difference between undercounter coolers. Some, by design, can not get below 40. We have a profile in the basement that will not go below 40. We like our drinks colder and sometimes keep dairy in an upstairs frig for guests, so need a real little frig up there. We have a magic chef in the kitchen that can hold 38, but I don't think they make it any more. We lay wine bottles flat on the top shelf, the middle is good for cans, the bottom is good for beer bottles. Great little unit. You don't want white wines that cold for long, so we only put the wines there we plan to consume in a few days. Here is an idea -- take out the top shelf when you have wine. Or, lay wine flat on the top shelf. Or, take out the middle shelf and put in a rack to make a shelf over the bottom shelf on one side and keep wines on the other side on the bottom.

Here is one meant for outdoors. Pricey, but holds beer if the last shelf is removed.

Summit outdoor beverage

Here is one -- 30 inches. The shelves adjust. Looks like it fits your container requirements. I don't know about the temp it can hold.

wine one one side, cans and bottles on the other

Here is a Uline. Pricey, but looks like what you want and can go to 34 degrees. I am actually quite smitten with it after seeing it. Super pricey though. Uline

Nightowl, you are amazing. Thanks for all the feedback. You are spot on about the Summit one with wine on one side.. I found that last night while searching. Xedos, thanks for your reply too. Thought about the sub0 drawers but very expensive for what we are doing. Already have to go for the 30" freezer drawers to solve something else. Although the beverage unit will be right next to the freezer drawers and look super sweet, it is not in the budget.
