Convert Approved Issues to Projects: One Scenario or Multiple?

We're using the Workfront - Convert Approved Issue to Project template and trying to determine the best architecture in Fusion.

We have:

• 1 Request Queue
• 9 Request Forms
• 30+ Project Templates

Each request form should map to the appropriate project template(s) when the issue is converted to a project.

Would you recommend:

• One scenario with filters/routers/switches to determine the correct template?
• Multiple scenarios dedicated to each request form?

Looking for insights on what is easiest to maintain and scale over time. Thank you!
