There are no tooltip information dialogs like what you describe. You can right click buildings to get all the information you need about them, however. The most that could be counted as a "tooltip" would be the informative bits of text when you hover over buildings when you have a particular overlay active (eg "This building is slightly damaged" if the Damage overlay is enabled)

There is no information provided in game about the ratio of farms, markets and granaries you need, this is something that you have to work out for yourself as part of city planning and development, as the difficulty levels in-game (Very Easy through to Very Hard) change how much goods that a house consumes per year. The number of workers also affects the output of buildings (if you don't have full employment, then they work slower and produce less per year), as well as a range of other factors.

Keep in mind that Grand Ages Rome uses a radius mechanic while Caesar III uses a walker mechanic. You can have plenty of farms in Caesar III but an inefficient road system so that goods do not make it where they need to go in a timely manner.
