What is the idea behind AWS-Specific Parameter Types?

During my foray into Cloudformation I came across the AWS-Specific Parameter Types which can be used in the parameter section. But I somehow cant grasp completely the idea behind these constructs. For me Parameter have a specific value I want to pass on when creating a resource.

What is the point of AWS::EC2::Instance::Id or List<AWS::EC2::Subnet::Id>?

As far as I understood it's a kind of pre-check of sorts...

When would it make sense to use these AWS-Specific Parameter Types?

Thank you in advance A

The CloudFormation user interface uses these types to present a better experience, such as a pull-down list.

Then there is the ability to Query for the latest Amazon Linux AMI IDs using AWS Systems Manager Parameter Store by using:

AWS::SSM::Parameter::Value<AWS::EC2::Image::Id>
