Fantastic find Constantinus! It seems as though the downstretched arm held either a spear or a bow. The fact that there is a hole for a supporting pin in the back as well as the front of his fist pretty much eliminates a sword, as the back of the sword's hilt could have been easily cast into the hand.
Assuming he is holding either a bow or a spear, it seems unlikely he would be holding another weapon in his other hand such as a club, as it would have to be pointing forward and upwards, putting the whole sculpure out of balance. My guess is that he is holding a bow in the downward arm and a quiver in the other (with perhaps with a solidly formed group of arrows which have long since broken off.)
Some of your guesses seem to fit, but have you considered also Ares, Teukros, or Dionedes as the subject?

Johnnyi Hello! Ares is one of the safest candidates for several reasons, first is that the figure appeared in the Iberian pre-roman city (though Greek influence to have around the city of Emporion) who were very warlike people, over 50% of Hannibal's soldiers were trying to invade Rome Iberians in my area, for this reason can deal with the god Ares. (a god of war very fair that was adored by the mercenaries)
The second reason is that in the left hand is holding a sword.
But he had discarded for not showing many sculptures and always appears with the helmet, very few thus beces the esculrura only know that I show.
