In smaller airplanes where the propwash flows over the control
surfaces, your elevator and rudder are more responsive at higher RPMs.

I'm surprised that propwash would matter, since the airflow from the
prop should stay in roughly the same place no matter what the attitude
of the aircraft.

Propwash matters for a number of reasons. The more slugs of air
deflected by the control surfaces, the more force they exert, ant thus
the more authority they provide in controlling the aircraft. Propwash
also reduces stalls (wing and elevator) by providing increased airflow
parallel to the aircraft's longitudinal axis.
