In an emergency, put it on scan, and talk to whoever you can here.

Obviously, I am not going to be able to talk directly to a controller,

That's my emergency plan too.

Do airliners or other aircraft routinely monitor 121.5?

Just get the local center frequencies from a Low Level chart, and
start making mayday calls.
