In the spirit of how Docker is meant to work, I'd suggest some consideration should go into running only the UniFi controller in this container, and to link to a Mongo service running in another container. This can leave it to the end user then to decide how to deploy Mongo, or in scaled environments how to schedule the containers.
In my humble opinion, this unnecessarily complicates this particular package. The joy of this solution is that it is a one-stop shop. Your points are valid in a wider scheme, but in this particular case, anyone that is planning a Unifi installation so vast that it needs a separate MongoDB installation, could surely figure out how to do it anyway.
