Alright, I think I'm ready to vote. I'm still reading, so I may swing one way or another as time goes on, but I'll vote now, and explain my current reasoning. If any of you want to try and sway me, that'll give you a basis to try, or maybe point out flaws in my thinking.
So, my biggest concern going forward is freedom of movement. For me, the quest picked up a lot after we left Sylvania. Going to new places, exploring new areas, finding novel research, going on expeditions. I loved those parts of the quest a lot. I really want a job going forward with freedom of movement, getting to see new places and do novel things; the Swamp Town thing would match this goal well, except it discards far too much of our current foundation for my tastes.
That gives 3 jobs that meet my priority: Loremaster-at-Large, Mandred's Super Nanny, and potentially the Waystone Project.
Now, between the three, Loremaster-at-Large would be great, but it is more of the same. We are really, really popular with Dwarves. As a human, we've done more for the Dwarven Polity then could ever be expected of us, whereas we've had very little interaction with the Empire and large, and None with the Elves. That gives Super Nanny and Waystones the bump in my book.
I'd love to see the other provinces, and being the Imperial Fixer matches Mathilde's skills to a tee. We'd be tearing through Chaos cultists, rat infestations, vampire conspiracy and throats, or helping resolve the Marienburg situation. Sounds great to me. I'm also interested in getting to know Heidi better. She's currently in an extremely high position (Empress), and while she's working for Ranald, that doesn't guarantee she has the Empire's best interest at heart. What better way to confirm, that to work close with her for a few years:

I want more Elves. We all know humans, and we've been Dwarf-Quest for a couple years now, so I like Waystones for opening up the Elven factions. Boney is really good at characters an cultures, and I'd love to see his rendition of Elves with greater personality traits than "Prideful Disdain" you see often in their portrayals. That aside, the Waystones are a huge deal, and humans have almost no knowledge about them. They are keeping ambient magic to a level where daemons are unsustainable, and thus protecting the entirety of man, whether they are aware of it or not. A lot of the stability in the Old World is routed in these devices and humans have nothing to do with it at all. That a dangerous position to be in: to be reliant on things that we don't understand. To be honest, it isn't just humans either. The Elves and Dwarves have more knowledge sure, but not enough, not nearly enough. So, of the options, I think this one has potentially the largest impact on the greater world, barring the Skaven starting a war with humans in the next 20 years. So:
