Smaller, like one of the ones with the wires would be best imo. It has to go through the top zipper of the door and bottom zipper of the door once they're in the middle when it's closed.

I carry a small, travel lock when I think I'm going to stop somewhere. This won't stop a motivated thief (not much will), but will slow down someone just trying to ride off. It's cheap, and quite small and light.
I doubt that an ottolock or some of the other 'small' bike locks offer meaningfully better protection. This of course comes down to what the threat model is - these larger/more expensive locks are only a benefit for detering/preventing thefts from the threats that they protect against, and the lock below does not. My estimation is that these 'in between' threats are quite rare in practice.
