TGW is... twice as expensive as vpc peering?

VPC sharing is the sleeper here. You can do cross account networking all in the same VPC and skip all the expensive stuff.
as long as your VPCs aren't too big, yea.
Shared vpcs can get pretty big. Even if you approach the NAU limit you can use privatelink or TGW to have more large shared vpcs.
If you are exhausting an entire VPC I’d be pretty impressed!

And vpc sharing is free. Cost and architecture are tied.
More than twice as same AZ is free with peering. But if you're big enough you can get better deals on cost.
But unlike peering TGW traffic flows through an additional compute layer so it has additional cost.
