Lawn alternatives for the cottage?

Zone 6.

Recommendations for an evergreen ground cover that can withstand mostly sand, harsh winters, hot summers with full sun, barefoot kids and athletic dog zoomies.

Something that doesn’t need mowing, no flowers (don’t want everyone getting stung being barefoot)

And nothing too invasive, we do have neighbors.

In most areas grass doesn’t do too well, and areas it does grow it’s hard to maintain since we’re not there all the time.

Is there anything that checks all these boxes?
