Data transfer pricing over Direct Connect is lower than data transfer pricing over the internet
Maximum Resiliency (resiliency as much as possible) for critical or crucial Workloads
Separate connections terminating on separate devices in more than one location
Resilience to
device failure,
connectivity failure,
complete location failure

To connect multiple VPC ( Prod, Dev, Test) with On-prem and avoid resource sharing among the connected devices create an AWS Direct Connect connection and a VPN connection for each VPC to connect back to the data center. You cannot use Transit gateway here because you need to avoid resource sharing between VPC
