The primary difference betwen emphasis and importance in the spec is
that importance doesn't change the meaning of the text, but emphasis

Changing the importance of a piece of text with the strong element
does not change the meaning of the sentence.

The placement of emphasis changes the meaning of the sentence. The
[em] element thus forms an integral part of the content.

So I think <strong> is a better fit for your use case.
