The leaves & fruits details are not close enough to be certain. I’m guessing this might be the luster-leaf holly (Ilex laurifolia) or one of its hybrids? If this is luster-leaf holly, I can’t tell which one this is. Some of the cultivars include: ‘Mary Nell, ‘Alva’, etc… Check out the cultivar ‘Lea Bates’ from the included link below (scroll down to the bottom of the page). Best wishes!
