Chris, sorry about your wife’s bike being stolen. Here are suggestions for European city bikes with some of the features you want and enclosed chain case:
Pashley Princess (Bicycle Space are a Pashley dealer)
Gazelle Tour Populair (Daily Rider are a Gazelle dealer)
Velo-ce Draisina Classic (J.C. Lind in Chicago)
Alternatively maybe something more modern like a Priority Turi (from NYC) with Gates belt drive, an Enviolo/Nuvinci hub, and hydraulic disk brakes, and have Peter White Cycles in New Hampshire build you a wheel around a dynohub and supply a complete lighting system.
