The kubernetes provider, and kubectl works, but its not the nicest way of making changes. Its slow, quite clunky, and its not particularly intuitive. If your just getting started, and you know terraform its ok though. Its useful to bootstrap gitops tools like Argo or FluxCD though.

Helm diff will show you a similar diff to terraform. Running Helmfile in CD isn't a bad move, its really simple, and its a pattern that is easy to grok by any engineer. I think this is still a valid approach in a simple setup, its what some people call "CD OPS". It's a push model instead of pull, and there are downsides, but its not the end of the world.

Ultimately, at scale, i think gitops tooling like Flux and ArgoCD are some of the nicest patterns. Especially Flux's support for OCI artifacts as a source of truth. However then you will venture into the realm of kustomize, and much more complex tooling and concepts, which is not always worth doing.
