Start the car, leave it 10-15 seconds for the cold start routine to finish (notable change to the exhaust tone) and drive off gently. Keep engine labouring to an absolute minimum.
As for parking up, just drive gently and coast the last mile or so, and switch it off after a few seconds. These engine have an electric water pump that will run on if the engine (calculated EGTs) are very hot on switch off, otherwise its not needed. Unfortunately they do not have any oil circulating after the engine is switched off.
If you can't/haven't driven gently the last mile or so, I too would allow it to idle for a few minutes before switching off
