Unit files are supposed to be configuration files, people can override and extend if they want to make changes. It's not recommended to use the EnvironmentFile= logic to externalise configuration. Instead, just keep the config in one place, in the unit files, to make things less opaque and more uniform. And no, unit files are not supposed to be a templating language and do not support generlized variable expansion and quite frankly I should never even have added the limited env var expansion via EnvironmentFile= that ExecStart= supports, since it invites people to externalise settings that way.
