Great guide. Here's some stuff I thought of while reading:
1) Should maybe avoid saying things like civilian alerts are missing from "the premium version". They are just as missing in the free version as the premium. Makes it seem like premium is some different game. "Pay for less features!" aint a great advertisement.
2) Your note on tombs is a bit odd. The game never used to work anything like this. So to say "this is how it used to work and the bug will be fixed to make it work this way again" is kind of wishful thinking. Indeed it isn't even a bug. Just a really annoying result of having tomb setting be the same as bedroom setting (but with no "dormitory" option).
3) Bedrooms. You say "Smooth the walls, carve the walls" at the end but to really "bedroom like a master" you need to smooth and carve the floor before putting beds and cabinets down as dwarves will ignore areas covered by furniture. (And if you're making a pretty noble room, statues will block dwarves altogether so you'll end up with unsmoothed walls in the corners too potentially).
4) Barracks. Separate storage and sleeping area is a nice design. But the diagram seems to imply that you can't use a single barracks zone to do all functions (sleep, store, train). Which you can. Think this comes from yet another mythological "how to really get your military to work" non-existent bug workaround guide.
5) Oh, man you've linked to that completely cr*p "advanced marksdwarf guide" on the wiki which goes into great detail on how to work around bugs that were fixed about 10 years ago and completely messes up your archer dwarves. "Marksdwarf won't train if you give them a barracks and will use their crossbows as clubs" - absolute lie. Never mind, not your fault...
6) "a long travel distance for a well bucket can be slow". Not sure this is actually true? At least not to any noticeable degree.
7) "Except for the hospital, Locations are a newer game mechanic so expect some weird unintended behavior and bugs." - The hospital as a Location was introduced in 50.01 (was previously a zone, like a pasture) so is actually the newest type of Location. Others have had a long time to work through bugs.
(If you build a hospital from a dorm room, won't regular non-sick dwarves go sleep in it? Or do they avoid it once it's a Hospital Location? - never tried making it from a Dorm zone. Usually use a meeting area).
