Barracks aboard ships can be modeled after how crew quarters are done for those aboard ships today. Sizing them along these lines would/should allow for normal morale. Cramming them in would make for lower morale for most vessels. There are some exceptions, like how the old Skipjack class attack subs in the USN HAD to go with hot-bunking because the ships were too small to carry enough crew space. That's an exception. Quarter sizes have continued to grow as the technology allows for it and as society itself makes things like reasonable sized accomodations the norm. WW1 ships had men stacked 5-6 high in wire bunks slung throughout the ship. Space was cramped, food was poor, and morale wasn't always the best. Go further back and you continue to see cramped quarters, low morale, muntinies, etc. Always keep an eye on what's reasonable and go from there.
For smaller craft there's no reason why Medical-0 wouldn't be allowable - even for small passenger carrying ships. But at some point, say around subsidized liner or above, having medical-1 as a requirement is fair (or at a minimum an autodoc and/or the ability to freeze a passenger or crew member during transit). It's what we have today on cargo vessels with crews of 20-30. For some rescue or access to a doc is days away. So a good medical kit, access to tele-medicine and luck is what they go with.
Putting kitchen facilities in staterooms seems a bit... silly. Space is cramped on a ship, period. Passengers aren't going to cook their own meals, and neither would crew. They are too busy. Plus having a galley means crew and passengers socialize (or take their food to their cabin). This is common-sense design that has been there for a very long time. Some of the MGT explanations don't pass the common-sense test. Just like having each cabin a self-contained life support system to justify the high costs (especially when it's empty). Life support makes more sense as a shared facility. Otherwise your quarters would be limited by their water consumption abilities since space to store water would have to be in EACH cabin rather than a central shared supply. Then there is the matter of grey water being generated and instantly recycled? Makes much more sense to centralize things like that. Since canon is spread throughout multiple versions it's another thing to pass the reasonable test and go from there. Life support rules already conflict (costs, capabilities, staterooms vs. livestock carriers/slave quarters, etc).
