Back when the rumors about Assassin's Creed Origins started coming out en masse, one of them stated that the protagonist would be Israeli.
I tried to think if there were literally any other playable game characters who were Israeli, and even asked in the thread, but no one could think of any.
Later, I looked this up with someone, and the only examples we could find were Ash from Rainbow Six Siege (who is listed as an FBI agent despite originally being from the IDF) and apparently one of the nine character choices from Far Cry 2.
My working theory was that this must be one of the few areas game developers are uninterested in going as Israel seems unpopular on both sides of the political spectrum among younger people, whereas game developers feel they're only putting off part of the political spectrum when they have playable black characters or LGBT character or women.
I actually feel we do see slightly more Jewish representation generally (see Inuhanyou's post above), though you would be right in that it's still limited.
