As it happens, I’ve just had occasion to shop paddles recently myself and my usages are now similar to yours.
If you can get one (I like to buy from a dealer rather than by mail) I think you’d be happy with a Sawyer Voyageur. It is too delicate for much levering, but otherwise a delightful paddle to use. But I couldn’t get one through a dealer. I don’t know what’s going on with their shop but they were disrupted by fires in OR last year.
My favorite is a Grey Owl Guide (in Cherry) and has a lot of face area (as you like), but it is a deep water paddle and, like the Sawyer, is pretty delicate for levering. Its a “lively” paddle - with some flex and the grip is the most comfortable of any paddle I’ve ever used. I use it in shallows sometimes, but with care. I’m giving away my “secrets” here, but a deep water paddle used on a river can often give you forewarning of shallowing water and how far to skirt a sand or gravel bar by. You can feel your way to a deeper channel even when a slow moving surface gives little clue to guide. Not for boulders and whitewater, though.
Grey Owl Sugar Island is perhaps more in line with what you’re looking for, and is what I finally bought recently myself. Its pretty sturdy, not especially light, but has a good rock guard tip and partially around the edges.
The Bending Branches Java is similar to the Sugar Island, is a bit lighter and I’ve found it to be a bit more delicate.
Hope you find this helpful. I’m sure other options from paddlers where other makers are prevalent will present themselves shortly. Happy Hunting.
