Simple on QFE, but with QNH you need to think about it, whilst we are talking about VFR flight, why introduce an element of uncertainty?
But if what you say is true - that most circuit heights are 1000ft then is it not simply the case that when at circuit altitude, one will have to descend by 1000ft?
What VFR pilot descends from circuit altitude without being able to see the runway? One descends at the appropriate time at a rate that will cause the aircraft to land on the runway one is looking at. Can't be more simple!
Pilots who use QFE will generally depart using QNH. They will often plan the following;
Flaps up at 300ft AGL, turn at 500ft AGL, fuel pumps off at 1000ft AGL.
They then actually complete the above at 300ft AMSL, 500ft AMSL and 1000ft AMSL despite the aerodrome and terrain being some 200ft AMSL.

No. Some of us train PPLs to operate in accordance with their licence privileges.
