I would imagine airships are easier to autopilot and could be used for setting up automated warehouse to warehouse deliveries - including loading and unloading cargo, establishing a continuous flow of goods.
Maybe, but smaller blimps don't have very much throughput compared to trucks, much less rail. A Hindenburg sized megablimp that can actually carry a lot (but still way less than rail + trucks) is logistically difficult.
Seems like the niche is more point-to-point, where a large cargo needs to get somewhere unusual or unscheduled, and kinda quick. Something too big or too cheap for a helicopter, and maybe where a manned truck would not work or have a similar cost.
Maybe prefab structures too? All but the smallest dwellings are too bulky for roads.
if you are building new then an automated isolated railway network is not hard to achieve; and with any airship infrastructure you are pretty much building new anyways.
Main problem here is that it is a floating device. As soon as it unloads 4 tons of cargo it gets pushed up with 4 tons force upwards. And you'd better do not release helium to compensate that - it is quite expensive.
Without solving that problem airships are mostly for travel...
This doesn’t seem like the hard part.
Edit: sibling comment points out that helium can also be compressed. I don’t think “too much lift” is an intractable issue.
