I'm also trying to find something that basically does what you've requested. The options basically seem to be: touring/commuting tyre with a bit of tread (e.g., Marathon), CX tyre (e.g., CX comp), or MTB tyre with solid central tread (e.g., Landcruiser). The CX option seems to be lightest, although the touring tyre might give the lowest rolling resistance on road, since it's closest to a slick.
TBH, the only bike I've ever really understood that concept on is my 853 Sunday-best bike. On a day-to-day bike, which is primarily for commuting, I've generally found that there are so many other things contributing to the "ride" that one tyre being a bit more supple being another is not that big a deal.
That being said, I've only ever ridden standard Marathons, not the Marathon Plus. In more than 10 years of commuting I've had 2 punctures, both from things that would have stood a fair chance of going through a car tyre.
