I wouldn’t be overly concerned about changing the title. The relevancy between the two titles is close. While the page title is important, it’s not the only thing that is supporting the SEO on a particular page. I would be more concerned if you are changing the title, URL, content, etc., in combination as opposed to 1 element.
Hi @kwaddingham. I don’t believe changing the title to a more concise header will wreck SEO as you put it. With many factors going into SEO, one change like this won’t have a catastrophic effect positively nor negatively. In my professional opinion, it will however have a positive effect over time. Especially considering your proposed change looks better - it’s concise and understandable. My vote: change it!
