Is there a way to AWS services and it return the policy or role attached to it?

I have a use case where I am trying to use CLI to see the policies attached to each role that list write based policies.

However, the only data I hae is the service of the role. Opposed to the actuall role itself.

I'm wondering if there's a process to do this and receive this information for services such as Lambdas, EC2, and ECS instances?
