Very neatly done, just a few nits

I think the converters would be simplified by passing the BuilderType as the template parameter directly, rather than passing a trait with which to look it up. value_type need not be a trait member at all, I think:
inline const std::shared_ptr<DataType>& value_type(const std::shared_ptr<DataType>& type) {
if (type->id() != Type::DICTIONARY) return type;
return checked_cast<const DictionaryType&>(*type).value_type();
}

This is probably fine. Nit: I'd prefer to get the FixedSizeBinaryType inside the converter and use it's byte_width() over propagating the property to builders

The property is already exposed in FixedSizeBinaryBuilder.
Simple value types are supported: integers, string-like, decimal
