Just curious, why do most wired doorbells need a transformer, with the
associated hassle of wiring from a mains source to the tranformer and then
to the bell, when they could just as easily use a 9V battery in the
sounder unit instead?

I presume there's a good reason, just I'm too much of a numpty to work it
out for myself.

Probably because most (?) bell pushes have an internal lamp, so draw
current continuously. A battery wouldn't last very long!
