Strictly speaking, he's an AMF who's not moving around the central axis by default.
He behaves more as a wide AMF than, let's say, a SMF or a wide SS.
Furthermore, he plays somewhat similarly to a "Mezzala-style" CMF: He usually moves to wider positions despite not playing as a mere SMF, to the point of overlapping a bit the movements of the SB/SMF/WF at his flank. In that sense, he plays in a slightly more advanced role than the one of a Mezzala-CM, yet a bit deeper than a standard wide SS.
The rest of the suggestions seem reasonable enough though.
