Pedant alert, to be honest DD/MMM/YYYY is the most clear. when the DD is 12 or below its not abundantly clear whether you are in UK or silly US format.
Presumably, with a 'MMM' format, you're going to be using JAN, FEB, MAR etc, rather than 001, 002, 003, which would be kind of pointless when used to count to 12, so I'd fail to see any confusion.
01/JAN/2023 and JAN/01/2023 would both be perfectly clear, with NO confusion over whether the '01' is a day or a month.
