It is well-known that in his attempts to prove Fermat's Last Theorem (FLT) over $\mathbb Z^+$, Schur came up with a result that has come to be known as Schur's Theorem, which implies that FLT fails over $\mathbb Z_p$ for all but finitely many primes $p$. One might see this intuitively by taking any expression of the form $x^n+y^n-z^n$, with $x,y,z,n\in\mathbb Z^+$ with $n\geq 3$, then simply picking any prime factor of this number. Hence, we know that FLT does not, in general, hold in finite fields.
But surely there are cases where FLT does hold in interesting finite fields as well, other than just for certain choices of $p$ and considering $\mathbb Z_p$. What are some interesting finite fields in which FLT holds?
