Looking forward to this! I find myself nodding along with a lot of your observations and those in the comments.
I'll heartily second the ask for procedures for Trade - or perhaps more broadly what a lot of CRPGs cram into the "starport bulletin board" area: bounties, cargo delivery, passenger transport, escort missions, etc. These things tend to be rather template-y and fit nicely into the procedural framework ethos you have for hex-crawls or point-craws.
The other thing that might be handy would be "Patron" missions - where a randomly generated NPC offers a randomly generated mission ("mission target, mission activity, mission location, mission reward".) You could probably tie this into an expanded Faction procedures section - so the missions roll up to the Faction's goals, etc.
