When wiring new receptacles etc., what's the correct amount of wire to leave emerging beyond the face of the box? 6 inches? What's useful may be more than minimum code requirements.

You are correct. 6" is the minimum last time I checked. If you leave much more, however, you may find it hard to pack everything back in the box. In what circumstances would you find it more useful to have more?

For any box having an opening with any dimension less than 8", you must leave enough conductor so that it can extend at least 3" outside of the box. John is correct that if you leave too much, you will have trouble installing the device.

Yeah, snaking in a bunch of wire is a pest, and it fills the box rapidly. These are largely single gang boxes. I'll leave a minimum of 4" emerging, for potential screwups that require the wire to be trimmed (now or later), and probably not more than 6", since it gets too snakey.
