I don't think sum(strings) is beautiful enough

sum(strings) is more beautiful than ''.join(strings) in my view, but unfortunately it does not work even for lists because the initial value defaults to 0.

sum(strings, '') and ''.join(strings) are equally ugly and non-obvious because they require an empty string.  Empty containers are an advanced concept and it is unfortunate that a simple job of concatenating a list of (non-empty!) strings exposes the user to it.
