Here's one I think not many people think about, factory or industrial cycles, as in, they're used to get people and some goods around factories or industrial sites. In the open world these are often called transport bicycles, sort of like the middle step between your average bicycle and a proper cargo bike.
Transport cycles usually come with some sort of internal gear hub with 7 or 8 gears, mostly using the tried and true Shimano Nexus. Industrial or Factory bicycles tend to be a hell of a lot more utilitarian and built for shorter distances, with many of them being single speeds or maybe a 3 gear nexus in there. They're usually quite heavy, pictured one comes in at 19kg which is a lot for a non-ebike, but do sport some increased carry weights - 25kg for that front basket there, 140kg in total (so 120kg of load capacity including all human and all cargo), allthough I imagine this is often disregarded with very few problems.
typical dutch bicycles tend to have a bit lower nominal weight limits and the front rack often isn't part of the frame but rather it's own part affixed, allthough the lines do get blurry on that one.
Things like these two are more outside the norm, the first one is also a really common bicycle for postal services
I've been saying for years that the USPS should adopt more bicycles as part of its vehicle fleet. Especially in big cities
