For a 10 mile flat commute a hub drive would probably be all you needed but for less $ than a decent quality hub bike not often mentioned are the new old stock Yamaha Cross Core RC which are $1199 with a strong mid drive, hydraulic disc brakes, suspension fork which might be nice for commuting and 500wh battery. If your local Yamaha dealer has any in stock it might be worth a look. A somewhat local Portland dealer has them and I believe no sales tax in OR, although there might be a small tax imposed on an ebike. I've had an essentially same Yamaha mid drive on a BH (Spanish company) gravel bike for almost 6 years and can say it has performed excellently for me and the battery is still in good shape.
