> I would like to have a tool that generates the project structure for me, but I haven’t found one that fits me yet.

I recommend cookiecutter for this. I have a few templates I've built with that which I use frequently:

python-lib: https://github.com/simonw/python-lib

click-app: https://github.com/simonw/click-app

datasette-plugin: https://github.com/simonw/datasette-plugin

llm-plugin: https://github.com/simonw/llm-plugin

You can run them like this:

  uvx cookiecutter gh:simonw/python-lib
