For late-game megacities, the Imperial Cathedral acts as a "super-service" building, satisfying all faith and community needs for a massive area, allowing you to remove smaller chapels and churches. To help you choose the best start,

: Designate one side of your island strictly for trade routes (Pier placement) and the other side for your military Shipyard. This prevents pathfinding traffic jams.

Ensure Market Buildings (warehouses) are placed near your production buildings, not your houses. Citizens do not need warehouses; industries do.

If you prefer a city that looks like historical Venice rather than a min-maxed grid, prioritize waterways and plazas.
