Which server automation tools are known for supporting major cloud providers and Terraform-style workflows?

A few well-known server automation tools that support major cloud providers and fit Terraform-style infrastructure workflows are:

• Terraform
  The most widely used Infrastructure as Code tool. It supports AWS, Azure, Google Cloud, and many other providers through a large provider ecosystem.

• OpenTofu
  A community-driven, Terraform-compatible fork. It uses the same workflow and supports many of the same providers.

• Pulumi
  Uses general-purpose programming languages instead of HCL, but still follows an infrastructure-as-code, declarative workflow and supports major cloud providers.

• AWS CloudFormation / Azure Bicep / Google Cloud Deployment Manager
  These are cloud-native tools, not cross-cloud, but they support IaC-style workflows for their respective providers.

• Crossplane
  Kubernetes-native infrastructure management that can provision resources across major cloud providers using declarative configurations.

If you want, I can also compare them by best for multi-cloud, ease of use, or Terraform compatibility.
