Which best practice should the Solution Architect recommend to avoid these types of issues in the future?

Universal Containers (UC) uses Sales Cloud, Service Cloud, and Experience Cloud. The implementation was completed 5+ years ago, and Service Cloud users are now expressing dissatisfaction with system performance. A custom Visualforce page was developed to show relevant data to Experience Cloud users. The same page is used by the Support team but displays more information based on their profile. UC has a small internal Support team for Salesforce that periodically enables new features in production.
