Assignment rules and queue configuration are two options that should be used to help the support team work on some of UC's cases. Assignment rules can be used to automatically assign cases to a queue based on certain criteria, such as case origin or priority. Queue configuration can be used to add Case as an available object to the existing queue and specify which users or groups can access the queue. References: https://help.

Making a field universally required is a way to ensure that the field needs to be filled on every record; it prevents users from saving a record without entering a value in that field. It can be used to ensure that the billing system field needs to be filled on every invoice record by making it universally required in the field settings. Creating a process builder to set the field, defining an approval process for the child, or requiring the field on the record type are not ways to ensure that the field needs to be filled on every record; they either do not enforce data entry or only apply to certain scenarios or users.

Einstein Opportunity Scoring is a feature that helps sales reps prioritize and close more deals by assigning each opportunity a score from 1 to 99 based on how likely it is to be won. The score is calculated using artificial intelligence and machine learning based on historical data and patterns from similar opportunities.
Sales reps can use the score to focus on high-value opportunities and take actions to improve low-scoring ones. References: https://help.salesforce.com/s/articleView?id=sf.einstein_sales_oppty_scoring.htm&type=5
