[Warcraft] What could Arthas have done differently at Stratholme to lead to a better outcome, given the limited knowledge they had about the Plague and Scourge at the time?

Probably spent more than 15 seconds debating Uther and Jaina as to the merits of his plan.

Arthas was right; the only option they had at that point was damage control. If he tried a little harder than telling his friends "we need to kill everyone", he might have been able to convince them. He just did a shit job of articulating what he intended to do and why. In terms of actual actions, no, there was no cure available and at that point the Undead had basically succeeded. Having Uther and Jaina stand with him during that horrible event likely could have prevented his fall from grace and transformation into the Lich King.
