Deploying Microsoft Fabric items via CI/CD Using Python Libraries

For question one, I suiggest you look at dynamic replacements.
For questions two and three, my advice is to use a combination of the parameter file and variable libraries.
For question four, I tend to use notebooks instead. However, others I know tend to use parameter-driven approach from pipelines.
For five, it depends what you mean by parameter file structure.

One other thing, you migfht want to look into the config file functionality.
