* Just a normal executable rather than something that needs a separate runtime - yes I know Docker is near universal on Linux for developers but less so for users and it doesn't integrate well with user permissions.
* Works fine for graphical applications (again this is possible with Docker but not zero configuration).
* Despite your complaint about size I still suspect it's a lot small than a complete Docker image.
* Works natively on Windows, unlike Docker
BTW the ideal mode is standalone rather than onefile - this outputs a directory including your program and separate files for any C extensions modules. That will let you chase down the offending module(s) that are hundreds of MB. Which in your case there must be - I distribute a small Qt program and even that is only 10s of MB.
