Only advantage I can see the cave troll really having is size. Luke has him in speed, skill, durability, and quite possibly strength as well (been a while since I watched the LOTR films, so struggling to remember all the strength/striking feats).
Question is would Luke be willing to use lethal force in this instance, seeing as it's not a human opponent? Because morals could make a huge difference here, depending on how much damage Cage is actually willing to inflict. If he's not willing to really lay into the troll, he might get caught out in the process.

Cage is more than willing to lay into anyone, in character, to win a fight. And he’s perfectly capable of winning this one, for reasons you already pointed out.
Luke wins. He's far more durable than the trolls, and he seems stronger too. We saw that arrows could hurt the trolls.
