why do bathroom fans always come on with the light switch, when they are
most useful after the light goes out?

P.P.S: Venting stairway air to the attic? Have you looked into
using a thermostatically controlled louvre in the ceiling instead
of a fan?

Where would I find such a thing? Hadn't been considered, but now
maybe.

For the record, the fan has been doing an awesome job of cooling the
house "naturally", the inside vs outside temp "feel" is easily 10
degrees. Haven't found a thermometer to check the difference, but it
is worth the effect, it is just a matter of making the noise less.
