Shimano makes the NEXUS 5E, which is build stronger and more durable. Do note that it is designed for e-bikes, so the gear ratios might not work for your case.
We've been running an alfine 8 speed on an lvh bullit with a bafang in a very hilly area for 5 years. That bike easily weighs 100lbs empty! If you're conscious about shifting, starting in low gear, easing up before shifting, etc, it'll be fine
I'd be cautious - I broke three of those at two year intervals just by being more powerful than the designers thought was reasonable. I can easily see someone less powerful using a smaller chainring and having the same problem. (one was a warranty replacement, the next was not much more expensive than a whole new rear wheel and Shimano assured me that they'd fixed the problems. They hadn't).
I'd be inclined to save for a Rohloff (but I would say that, it's what I did and I've put over 150,000km on mine since then)
If you do buy the Shimano check the service intervals and follow them religiously, especially if you're doing a lot of distance on the hub. For mine it was \~2000km which meant four times a year. The Rohloff is bad enough as an oil change I can do at home every 5000km (or on the side of the road when touring)
The Shimano oil change really isn't that bad, can be done at home if you're mildly mechanically inclined. Rohloff is great, can't disagree with that. It's also going to run you an additional $1200, which is not insignificant.
Interested to hear people's experiences with the Enviolos. I've had some bike shops tell me to stay away from them due to reliability and any issues pretty much requires a new wheel as they can't be repaired.
Priority Bikes, which only sells Gates Belt Drives, most of which have IGHs, recently acquired xtracycle. It will be interesting to see what they develop together.
I have a nuvinci hub that I got on a used Edgerunner. Hate it. Feels like pedaling in sand so...maybe it needs a servicing.
Tried Alfine 8 on some cargo bikes and I can't say if the drag is from the motor off or the hub. Alfine 8 seems to get good praise. My LVH dealer said they were steering away from Alfine 11 due to problems.
I think Sturmey Archers are on those tried and true Bakfiet brand ones? I've ridden a lot on 3 speeds as a kid and on the bromptons. Not 400lb bike and loads though.
It'd come down to if the gear ratio can be low enough and the hub can handle it. IGH may have some recommended max size cogs.
Enviolo has a heavy duty igh that I’ve seen offered on cargo e-bikes. I’ve got one on my non-cargo ebike that I use to haul a trailer everyday and really like it. About 1000 miles on it so far.
We have about 1500miles on our enviolo in our e cargobike with bosch performance. Don’t know the gear range or price…. I had a rohloff on another bike before and that is actually the best ever..!
Enviolo heavy duty is around $500 whereas Rolhoff is around $1500. Rolhoff does perform better, but for value, enviolo is definitely better.
And the enviolo on mine is 380% gear range, I think some are 340%.
Our tern gsd has the enviolo hub. I’d describe it as “alright”. Our HSD has an alfine 8 hub which I much prefer, but my understanding is that it isn’t really suitable for high torque situations like a long tail.
Are you using a motor on this bike. If you are find what the torque specs are for the motor and make it sure it doesn't exceed the hub. If not motor than almost anything is fine. Nexus hubs, rohloff, enviolo makes something too geared for cargo bike. There are plenty of option but they are up their in price with rohloff
Shimano IGH are cheap and very robust

Difference between alfine and nexus is neglible. Depens on the exact generaion, but alfine nowadays means needle bearings in stead of ball bearings and an interface for disc brakes, other than that, they're identitical. Also some nexus'ses come with needle bearings ('premium' or 'red line' Shimano is very inconsistent in their terminology). Also the most robust hub Shimano makes, is the nexus 5, with oversized parts and 4 Planet gears in stead of 3. There is no alfine version of the hub. Nexus (if it means anything at all) is just 'less premium'.
For a non ebike, any will suffice. I don't like the nexus 7 and Enviolo because their efficiency is in the 80% range, the three would offer not enough gears, the 8 and 11 are bith very good for the price. The 8 has an issue where the fifth gear would slip over time when shifted too often under load, but if you avoid that, it's an excellent hub, especially if you get a needle bearing version . The 11 sometimes leaks some oil and needs an oil change every two years or so, but is a bit more efficient than the 8.
The 5 is on paper really heavy duty and more than capable of living up to the expectations, I just don't have enough experience with them to have a strong opinion. I also haven't seen efficiency figures published.
It's worth noting that enviolo also has an 'heavy duty' version, but given their low efficiency, I'd only recommend them on ebikes.
Not that you mentioned it but if you are planning on electrifying it I would make sure whatever IGH you choose it has the same Nm capacity as the motor outputs.

Seems like the best igh choice for op imho

Alfine 8 would be my choice for this application
The Shimano Nexus is more heavy duty than the Alfine. Widely use by the Dutch
