### What happened

Not really showing a failure in operation, but the code in the [`KubernetesPodOperator._render_nested_template_fields`](https://github.com/apache/airflow/blob/d26dc223915c50ff58252a709bb7b33f5417dfce/airflow/providers/cncf/kubernetes/operators/kubernetes_pod.py#L373-L403) function could be improved.

The current code is formed by 6 conditionals checking the type of the `content` variable. Even when the 1st of the succeed, the other 5 conditionals are still checked, which is inefficient because the function could end right there, saving time and resources.


### What you think should happen instead

The conditionals flow could be fixed with a simple map, using a dictionary to immediately get the value or fallback to the default one.

### How to reproduce

There is no bug _per se_ to reproduce. It's just making the code cleaner and more efficient, avoiding to keep computing conditionals even when the condition has been resolved.
