I can't find the circuit breakers for any of the upstair bedrooms in
this old, 1908 built house. Would it be reasonably safe to replace a
light switch wearing rubber gloves and rubber-soled shoes if it comes
down to having nno other options?

A single pole non-grounded switch has two wires attached to it. One the
hot feed and the other runs to the light.

Your chance of a shock are remote as long as you do not touch the bare part
of the wire or the bare wire to a metal part.

Assuming you do not a heart problem a DRY shock from a 110v circuit isn't
going to hurt you much anyway.
