What are the most appropriate license types for GS Tregional Leads and the GS Capacity Planners?

Universal Containers (UC) uses Global Shipping (GS) as one of their shipping vendors. Regional leads of GS need access to UC’s Salesforce instance for reporting damage of goods using Cases. The regional leads also need access to dashboards to keep track of regional shipping KPIs. UC internally uses a third-party cloud analytics tool for capacity planning and UC decided to provide access to this tool to a subset of GS employees. In addition to regional leads, the GS capacity planning team would benefit from access to this tool. To access the analytics tool, UC IT has set up Salesforce as the Identity provider for Internal users and would like to follow the same approach for the GS users as well.
