What sharing option is suitable for allowing 'Partner User' role users to access opportunities with a specific status?

The criteria-based sharing rule is an effective option for allowing users with the 'Partner User' role to access opportunities that meet specific criteria, such as a particular status. This type of sharing rule enables the organization to define conditions under which records should be shared with particular groups of users, based on the values of specific fields.

In this scenario, if you want to provide access to opportunities with a specific status, a criteria-based sharing rule allows you to set the criteria based on that status. This ensures that only relevant opportunities are visible to the designated users, focusing access where it's needed and enhancing data security by not overexposing all opportunities.

Other options may not serve this specific need as effectively. Ownership-based sharing rules, for example, depend on the owner of the record rather than the content or status of the record itself. Super User Access is a general concept that might grant broad permissions, but it doesn't specifically cater to selective access based on record criteria. Similarly, Account Role Optimization does not provide the mechanism necessary to define access based on specific attributes of opportunities.
