Do I Need ARIA Tags for a Simple Section in HTML?

You probably don't need any `aria` tags here since your example is mostly just content. The tags you're using are already doing a good job for accessibility. `aria-label` is useful when the element's content isn't clear on its own, like for a button where a short label might need more context. For instance, you might have something like `Short label`.

It really depends on how important the content is. The section header could act as a label for the section, changing it from just a standard element into a more significant region. Using ARIA can help identify these sections more clearly if they hold importance.
