This is the webpage of TFHE, a recent and quite fast FHE scheme - https://tfhe.github.io/tfhe/ . They have a (surely incomplete) list of applications. I work in a somewhat related field, and I know that current FHE schemes can be used for things like voting and computing basic statistics when the data size is smallish.

Out of that entire list, all of them are either academic projects or toolchain projects. None of them are FHE in use in an actual production system.

FHE is interesting but very early.
