Hi Renato,
1. Status is the OOB field of the records of Dynamics 365. It is essential for the case. Each case has a value of Status, which shows whether the case is active, resolved, or canceled. These indicators are set using the Status and Status Reason fields, which are also linked together.
Note that Status is a case field that has a specific value that we can use to filter cases. Administrators or managers can make case reports based on this.
Please refer to this article on Status and Status Reason:

2. You can help ensure that people enter data consistently and follow the same steps every time they work with a customer by creating a business process flow.
Business process flows provide a guide for people to get work done. They provide a streamlined user experience that leads people through the processes their organization has defined for interactions that need to be advanced to a conclusion of some kind. This user experience can be tailored so that people with different security roles can have an experience that best suits the work they do.
Note that Stage is not the case field, it has no value. So we can't filter the cases through the Stage.
Please refer to this article on Business process flows:
