[Python] What's the best practice of typing hint after python 3.9?

After python3.9, there are at least three ways to use typing hint. Take the build-in collection set for instance:

# way 1
def f(s: set[str]) -> str:
pass

# way 2
def f(s: typing.Set[str]) -> str:
pass

# way 3
def f(s: collections.abc.Set[str]) -> str:
pass

# way 3': or arguable collections.abc.MutableSet vs collections.abc.Set
def f(s: collections.abc.MutableSet[str]) -> str:
pass


Furthermore, for some abstract type there are two version in typing and collections.abc, take Mapping for instance:

def f(m: typing.Mapping[str, int]) -> int:
pass

def f(m: collections.abc.Mapping[str, int]) -> int:
pass


According to The Zen of Python:

There should be one-- and preferably only one --obvious way to do it.

I am confused which one is best?
