We've had similar struggles and something like a babboe or urban arrow won't fit. I was 95% close to ordering a Libelle https://leichtlast.de/ The non-motorized unsplittable version weighs around 20kg, the splittable slightly more, but it is splittable.

We then settled for a Muli https://muli-cycles.de/en/

I still sometimes think the Libelle would have been cooler but the motor is stronger on the muli and I'm very happy with it too.

I really like the cargo basket on the Muli. I've kind of had my eye on the Omnium (https://omniumcargo.com/de/shop/produkt/cargo-v3-wifi/#frame...), there's a hinge attachment for the rack which can make it a lot narrower. (https://damgood.bike/products/ouch-1-omnium-utter-cargo-hing...)
