Maximal families of Calabi-Yau manifolds with minimal length Yukawa coupling

For each natural odd number $n\geq 3$, we exhibit a maximal family of $n$-dimensional Calabi-Yau manifolds whose Yukawa coupling length is one. As a consequence, Shafarevich's conjecture holds true for these families. Moreover, it follows from Deligne-Mostow and Mostow that, for $n=3$, it can be partially compactified to a Shimura family of ball type, and for $n=5,9$, there is a sub $\mathbb Q$-PVHS of the family uniformizing a Zariski open subset of an arithmetic ball quotient.
