How would you wire this ?

If the unit was in a garage I would do that. This is a portable unit that he uses in a basement mini-kitchen. He rolls it in, makes his beer and puts it away when he's done. Installing a stainless disconnect is out of the question. Thanks for the thought anyway.

If on 2020 NEC all receptacles in basements need GFCI regardless the room type/usage.

Whether that makes any sense or not it is what they did there.
