Comprehensive Detailed Step-by-Step Explanation with All Enterprise Geodata References:
AnEnterprise geodatabaseis the most appropriate choice for this scenario due to the following reasons:
1. Requirement to Store Data Locally on Organization's Servers
AnEnterprise geodatabaseallows organizations to store GIS data locally in their own database management systems (DBMS), such as PostgreSQL, SQL Server, or Oracle.
This meets the requirement of maintaining control over data storage and ensuring the data resides within the organization's infrastructure.
2. Editing GIS Data via Web Services
Enterprise geodatabases seamlessly integrate with ArcGIS Server, enabling data editing via web services.
Organizations can publish feature services to allow authorized users to edit GIS data in real-time or in a disconnected environment (via sync).
These services support advanced editing workflows, including versioning and conflict resolution.
3. Indexing Specific Business Fields for Performance
Enterprise geodatabases offer robust indexing options to enhance query and editing performance.
You can:
Create attribute indexeson fields that are frequently queried.
Usespatial indexesto improve the speed of spatial queries.
This level of customization helps meet the performance demands of specific business workflows.
4. Advantages Over Other Storage Options
File Geodatabase:
While it is suitable for smaller datasets and local storage, it does not support multi-user editing, integration with web services, or advanced indexing for business fields.
Hosted Relational Database:
This option is part of ArcGIS Online or ArcGIS Enterprise managed services and stores data in the cloud, which contradicts the requirement for local storage.
It also does not provide the same level of control or indexing capabilities as an enterprise geodatabase.

Conclusion:
AnEnterprise geodatabasenot only meets all the stated requirements (local storage, web service editing, and indexed fields for performance) but also provides additional scalability, security, and multi-user editing capabilities.
