I honestly don't think Fury can hang with the top heavyweights of the new generation (Joshua, Wilder, Ortiz). I would favor Klitschko in a rematch against him too.

If Fury intends to resume his career, his best bet is to grab the biggest payday, which would be against Joshua, before getting exposed. I wouldn't have him take any tune-ups, as he very easily could be upset. Just look at his fight against longtime cruiserweight Steve Cunningham, who was good but dwarfed by Fury and should have been overwhelmed but actually put Fury on the deck.

Of course, I personally would rather see Joshua in against several others before or instead of Fury.
