Enforcing organizational data governance policies across Azure Databricks workspaces can be effectively achieved by utilizing Azure Policy to audit and enforce compliance on Azure Databricks resources. This approach offers several advantages:

1. Centralized Policy Management: Azure Policy provides a unified platform for defining and managing policies across Azure resources, including Azure Databricks workspaces, ensuring a single point of control.

2. Compliance Monitoring: It enables continuous evaluation of resources against defined policies, ensuring consistent adherence to data governance standards.

3. Policy Enforcement: Azure Policy can proactively enforce policies by denying non-compliant resource creation or modifying resources to meet compliance standards, thereby maintaining data integrity and security.

4. Customization: Organizations can create custom policy definitions to address specific governance needs within their Azure Databricks workspaces.

5. Integration: Azure Policy's seamless integration with Azure Databricks allows for direct application of policies to Databricks resources, simplifying enforcement without complex configurations.

This method stands out as the most suitable due to its comprehensive features that support centralized management, monitoring, enforcement, customization, and integration, making it an efficient solution for enforcing data governance policies.
