If I expose to preserve highlight detail I usually pull contrast down to minimum and modify the gamma to restore the brightness balance, sometimes I need to resort to curves but it usually always provides decent outcome. Shooting digital is quite different to shooting film and the 18% (or whatever it is) gray metering point is largely irrelevant, not clipping the sensor and minimizing noise is important.
