Unsure about the uselessness of food producing buildings outside your production city, eg Granary (-1G +2F).
Costs 1 gold to produce 2 food which allows you to scrap a farm for a trading post (-2F +2G). This the benefit of an additional gold and modifier bonus on the original 2 (so with marketplace this would be +1.5G overall).
Also the return is increased before civil service improves farms (-1F +2G), a net benefit of 3G as it allows the removal of 2 farms
The return on the other buildings is minimal and therefore low priority (plus they make it harder to manage your happiness cap).
