On the sugar water: I'd leave it out. An open bowl of syrup gets robbed hard, pulls in wasps, and can carry disease from one colony to the next; beekeepers who need to feed do it inside the hive. Clean water near the flowers, like your wildlife pan, is the better draw.
Seeing almost no bees can also just be the season. In a lot of places mid and late summer is a dearth, a stretch with little in bloom, and the bees are fewer and quieter then. Whatever flowers in your emptiest month is worth more to them than one more spring bloomer, and letting herbs bolt, as Tereza says, is one of the easiest ways to fill that gap.
