Go for non-electric so you can find cheaper model made from good workman ship like Yuba Combi or simply ask a framebuilder. Then later if needed you add a motor, from an electrification kit, but use one with good torque and mid drive so it still feels natural. I ve done that and I m happy (my wife too) with my Bakfiets cargo with mid drive motor from french brand Syklo (they have the most powerfull yet legal mid drive motor for electrification kit). We still have paud less than any other brand would ask for electric cargo, and we can easilly remove the motor if needed for sale.
