I imagine there's a lot to go into it. For example, if it's a one-of-a-kind weapon with a long lead time to develop, they probably have a pretty low risk threshold.

Exactly, but what if you're sending dumb munitions, a couple of tanks, or relief to a disaster zone?

You could spare to blow all that during takeoff. Whatever, let's try again in four hours.

Launch windows generally aren't open-ended and typically only last a few hours because they are orbit-dependent. That's why when a launch is scrubbed, a window often doesn't open again until days later.

I doubt that matters for point-to-point deliveries like this.

The GP comment was making the point of keeping Starship in orbit for deliveries to mitigate the launch window risk.
