Like others have said, my expectation would be to see a full strength side - they need the game time together before they get a rest. Unless you count Naholo as being part of our 'full strength' team but he won't be ready until later, and you could also quibble over whether Crockett or Woodcock should start. I'd be inclined to give Crockett some catch-up game time against Namibia and Georgia instead, and revert back to Woodcock when Tonga roll around. SBW was pretty strong last time they faced the Argies, so if they take precautions for Nonu then I'd choose Williams over Fekitoa.
If momentum seems to be with us then I wouldn't mind seeing a few cheeky drop goal attempts. I'm not saying DC is legendary at them, but he needs to try a couple of times imo. If things get super close in a knock out game then we need to feel comfortable-ish about it. I'd also say extra focus should be put on the scrum, and interpreting Wayne Barnes through whatever analysis they do (as sad as that sounds). I suspect we'll win, but I wouldn't put it past the Argies to make it scrappy.
