There would never be a reason to use "fu" as a prefix. "u" is only
needed for python 2.x compatibility, and this feature is only for 3.6+.

Well, if we generalize this to something more than just literal string
formatting, maybe so. Until then, for the explicit version (as opposed
to the "all strings" version), I like "f". When I'm done with that PEP
we can start arguing about it.
