The title is written for the search results page and the H1 for the visitor who already clicked. Making them byte-identical wastes a second chance to describe the page, while sharing no vocabulary at all suggests the two disagree about the topic.
Keep the shared subject in both, but let the title carry the search phrasing and the H1 the human phrasing.

Twitter card type is declared
Without a card type, X renders a shared link as plain text even when Open Graph tags exist. It is one line of markup that decides whether the share carries an image.
URL is short and readable
Long parameter-laden URLs get truncated in results, are harder to share, and multiply into near-duplicate variants of the same page.
Page is not blocked by a robots meta tag
A noindex directive removes the page from search entirely. It is the most damaging single line on a page, and it is nearly always left behind by accident after a staging deploy.
Page has a title
The <title> element is the headline Google shows in search results and the label the browser puts on the tab. A page without one is listed under a machine-picked fallback that nobody chose.
