Well done OP. You've managed to impartially parse out what YOU want in a bike, not what the industry trolls say you need and you wound up with a great bike which I think will suit you for years to come!
I want you to update us on the Alfine hub. IGHs have long interested me but; however, Shimano advises against "hard pedalling" on these hubs (or maybe just the Nexus). That's a bit of a deal breaker for me - I commute too, I don't race but there are moments when I ABSOLUTELY MUST CLEAR THE INTERSECTION or maybe I just want to stomp over an overpass as opposed to downgearing.
In the future, you can swap it out for a Rohloff Speedhub and truly have your forever bike at that point!
Cheers and happy commuting in 2020 in New England from here in the PNW!
