Just to clarify this point: If 0 is not the first key, then it's not a list.
After filtering a list, you get an array that may or may not be a list:

Regardless, to add my 2 cents, I'd keep things simple and vote for this
signature:
array_first(array $array): mixed
array_last(array $array): mixed
returning the first/last element, or
null if the array is empty.
Or, alternatively:
array_first(array $array, mixed $default = null): mixed
array_last(array $array, mixed $default = null): mixed
returning $default if the array is empty.
Both look fine to me.
