Been a couple of years since I used AWS and I remember when CDK was just coming out. My big question at the time was whether or not the CDK would alert you to errors at compile time and save a bunch of whaling and gnashing of teeth that comes with Terraform.

Yeah it is much more mature now. Basically the CDK will generate YAML cloudformation templates at compile time so any errors are generally caught then. If you utilize typescript it is even safer since you know there are no missing parameters or anything like that.

I have not used terraform that much, but they did launch a CDK for terraform that does a similar thing https://www.terraform.io/cdktf. Basically you write in code and at compile time it converts it to the terraform templates.
