A Docker container starts in two seconds or so. And gives me everything I need. So no need to dabble with a VM.

There is not much overhead in running a project in a container. The project has a setup file that turns a fresh Debian 10 into whatever environment it needs. And thats it. Run that setup script in your Dockerfile to create a container and you are all set. Want to run the project in a VM or on bare metal? Just install Debian 10, run the setup script and you all set.
