More mutually exclusive buildings?

[rattatatouille]

In Civ VI, one thing that came with city unstacking is delineating building lines alongside districts. Thus, we have the Library > University > Research Lab line within the Campus, the Market > Bank > Stock Exchange line within the Commercial Hub, and so on.

One special case is the Encampment building line. It surprisingly has four buildings, but two of these are mutually exclusive: the Barracks and the Stable. Both do the same thing (production bonus and added XP for units), but affect different unit lines (melee/ranged and mounted respectively). Being forced to select between two beneficial bonuses is something interesting, and here are some more buildings of this ilk I'm thinking of:

* Bank and Guild Hall. The Bank grants a smaller, but more reliable Gold Bonus (+3 GPT), while the Guild Hall ultimately grants a larger bonus, but only if it receives a foreign Trade Route (+2 GPT base, additional +3 GPT if receiving a foreign Trade Route).
* Research Lab and Public School. Both provide bonus Science, but the former grants a production bonus towards Spaceports and its associated projects, while the latter also provides Culture and a free Great Work slot. The implication is simple; the former allows you to go for a Science Victory more easily, while the latter helps with a Cultural Victory.

So, what other building choices can you suggest?

Temple vs. Festival Ground: The Temple receives its current bonuses- faith, great prophet points and the ability to purchase advanced religious units. The Festival Ground lacks these bonuses but doubles Pantheon effects in its city.

Stock Exchange vs. Commodity Market: The Stock Exchange keeps its current flat gold bonus. The Commodity Market grants +x gold to each copy of the city's most abundant resource, where x is the number of that resource in the city (so a city with 3 wheat would receive a total of 9 gold).

Overall I feel like the choices they've made so far make sense, for the most part. I really like the museum dichotomy. The only way to make more exclusive buildings would be to split what's already there:

• Research Lab: split into Biochemical Lab (science and amenities) and Physics Lab (science and production) (both negatively affect faith).
  
• Zoo: split into Zoo, Aquarium, and Gardens.
• Stadium: split into Stadium (amenities), Mall (gold), Theme Park/Resort (tourism).

Also, I think the entire Industrial Zone could be split off into a new district:

• Energy Grid (same category as Industrial Zone): Recycling Center; Biorefinery; Hydro Dam/Windmill/Solar Park/Geotherm Pump

Auction Room (Commercial Hub building, cannot be built if City has a Bank): Provides one slot for Great Works of Art. Filling the slot grants +2 ammenities in the city.

Slave Market (Commercial Hub Building, replaces the Market): Provides +3 housing and +2 food to the city. Requires Autocracy, Oligarchy or Theocracy government types.

Scribal School (Campus building, cannot be built if City has a Library): +1 science for every four citizens in a city, provides points towards Great Scientists and Great Writers.

Gymnasium (Entertainment Complex Building, cannot be built if City has an Arena): generates +2 loyalty and +2 food.
