To find out more details about a change made to a field type of an object in Salesforce, the Setup Audit Trail is the most appropriate resource. The Setup Audit Trail provides a comprehensive log of all changes made to your Salesforce organization's setup, allowing you to review who made each change and when it was made. This can be particularly useful for tracking changes to metadata elements, such as field types, which can impact functionality within your application.

Each entry in the Setup Audit Trail contains information on the specific changes performed, making it straightforward to identify modifications related to field types. This is essential for debugging purposes, as understanding when and how a field type was altered can help in troubleshooting and determining its effects on your application and business logic.

While the other options such as Debug Log and System Log provide runtime information and errors that occur during the execution of code or processes, they are not focused on administrative changes or metadata alterations. Field Level Security pertains to user permissions for specific fields but does not provide logs of changes made to field types themselves. Thus, for the specific context of field type changes, the Setup Audit Trail is the recommended source for obtaining relevant details.
