> I think it's more natural to think of arr[i] as “the ‹i›th element of arr” because it doesn't require explaining what a step is or what the beginning is.

Yes, but if you will eventually need to do steps on your array, you better opt for the framework that handles them better. I agree, that if your only task is to name them, then 1 based indexing makes more sense: you do that since diapers, and you do that with less errors.
