I'd like it if elected/in-fort-appointed positions could be linked to room-holdings (and thus things within them) by the position not the dwarf.
When the mayor changes, for whatever reason, I currently need to notice and do the reassignment of rooms myself. Perhaps giving the old incumbant the new one's "civvy" quarters, if applicable. I wouldn't mind maintaining normal accomodation for everyone and then whoever-happens-to-be-mayor (or other 'noble' positions) gets the room(s) assigned to that noble-position (ditto record-keeper, broker, whatever). Bad thoughts for the outgoing incumbent getting the downgrade, unless you let them down gentler by a 'retirement' improvement to their more personal holdings.
There could be a choice to create and fill speculative rooms to satisfy the remote royals (whether expected[1] to arrive or not[2]) so that if they did arrive (perhaps actually drawn to sufficiently blingified suites) they already have a place to praise or condemn the value and beauty of. Optionally, entourage facilities too (separate office for the consort, chambers for ladies/gentlemen-in-waiting, a mini-barracks for accompanying bodyguards).
Furniture requirements could specifically include a pedestal/display-case for (and, for bonus points, housing) some form of regalia like a much-improved scepter. Of course it would be a full-on thief-magnet, at least when not actively patrolled by the Royal Guard and others legitimately hustling and bustling in service of the monarch-in-residence.
And if world-events raise a local to the crown, they also gain access (and use), naturally. At least until it's time to move on to review/sample other such facilities around the kingdom.
(When it comes to inheritance, at least, I suppose tombs should be codified or kption-set to be exempt as soon as death happens and the old owner is bodily assigned to it personally. You'd need to line up another tomb (or a fresh sarcophagus, that can reassigned to be the new focus for the same catacomb), to perhaps end up with a grand Hall Of Ancestors.)
So, yeah, regalia (royal scepter, mayoral chain(/necklace?), bookkeeping tome, CotG's ceremonial armour, ..?) and rooms.
[1] A 'Royal Progress' might happen. Various British stately homes have rooms or extensions that were built in the knowledge that the monarch would be visiting (with foresight such as 18 months notice, however these things were organised behind the scenes), stay a few days then move on. Preserved examples of 'temporary' Royal Quarters have been maintained for hundreds of years.
[2] Other manorial/castle-based 'seats' built Royal Accomodation in order to tempt the reigning monarch to visit. Which didn't always(/often?) work. But may still have been largely preserved by subsequent tradition, at least until the next major remodelling or destruction of the property.
