I would doubt any certified wall wart would catch on fire if the output is dead shorted. I would think that any device with "user accessable" electrical contacts would be designed with the expectation that the user will sooner or later short the contacts.
Consider the daffodil. And while you're doing that, I'll be over here, looking through your stuff.   8)

If I end up going with the wall wart I have, should the fuse be placed on the positive wire or the negative one?

Thanks!

Makes no difference, the same current flows through both wires. The convention is to put it on the positive, if the circuit it powers uses a negative common.
