AWS Transit VPC vs Transit Gateway use cases and limitations

Please clarify the differences and highlight the advantages and limitations of these two solutions.

If I recall accurately, Transit VPC had a bandwidth limitation for each VPC connected to it. Not sure if the same is true for Transit Gateway, since it accommodates auto-scaling, but there are still limitations on VPN connectivity to spokes.

 

Also, I am having trouble figuring out how either solution would fit into a multi-region implementation with Direct Connect gateway, as depicted here:

As well as how to connect a VPC containing public-facing web servers protected by AWS WAF to the CP Transit Gateway for internal communication only, (i.e. routing access to the back-end servers and the Internet via CP, but preserving inbound traffic from the Internet to LBs and the return traffic).

Thank you,

Vladimir
