It would appear there is no right or wrong way.
How I/we do it: In daytime ops. we have beacon and strobes on prior to starting - On a busy apron in the light of day we find a beacon and/or nav's arn't obvious enough especially with some a/c parked 3 or 4 deep on the apron. At the holding point - All remaining lights on (Landing/Taxi/Nav) where they stay on for the whole flight as the local training and circuit gets quite busy too.
At night we never use landing/taxi out of consideration for others.
