Falcon Heavy is intended for flying payloads that are very large or required very high energy orbits. For smaller payloads, Falcon 9 is more cost-effective, which is why SpaceX uses it for Starlink currently. However, if Starship works, it will drastically reduce cost to orbit and become the workhorse for basically all launches.
