A steam engine meant that a factory or mill no longer needed to be built close to a lodge, reservoir or running water to drive a waterwheel. Coal could be delivered, and water for the boilers could be piped over long distances.
Steam engines do not need to be built next to rivers or streams.
It provided for the first time in history, a steady, reasonably reliable power source that could be designed to suit the application and requirements, and was not subject to the obvious geographical limit of necessary proximity to a river suitable for water-power.

You should clarify, advantage compared to what: for instance muscle power, gasoline engine, etc.
The advantage is the crank has to turn less between power strokes so it runs smoother, and one disadvantage could be it takes up a lot of room in the engine bay.
Steam-powered factories could be built in cities.
carrying power
Maximizes torque/power out of the engine by increasing cylinder filling (volumetric efficiency).
That isn't always true. An engine with a larger displacement has an advantage but there are other factors that can increase power in a smaller engine that can out perform a larger engine.
