Listen, there are hardly any options, and the ones you have mostly require you to spend almost an hour to complete. Add in stuff like driving cities that are closer, heavy / special transport runs, and more!

Actual suggestions of "I think X should be a category because of Y" would be more appreciated than statements like "Add more".

If you look at the leaderboards, pretty much all of the runs are much shorter than an hour. The 5/10 Delivery categories are very short, and all of the Point to Point runs - even Roswell to Seattle - come in under an hour in real time, as does Idaho Viewpoints. The Career categories are the only longer categories, but that is expected. If you have any genuine suggestions of other destinations or category ideas, I would be interested to hear them either here, or in the discord, but ideally we would want any additions to have something 'special' about them, since otherwise the permutations of city A to city B are endless, and that gets pointless.

Special Transport deliveries are not particularly exciting to run or watch, given you must obey most road rules and cannot go too far beyond the speed limit. Heavy delivery options are theoretically more possible, as they can be engineered using a save game editor, but the issue remains in having something compelling that would be interesting to see run.
