Welcome to the Q&A Forum

Hi, It's not really a SERP destination feature, it's basically an extension on the knowledge data that Google has. If you Google for example: seo software you'll likely get a similar setup with a carrousel with the top software for SEO. It's incredibly hard to get as it seems to be information that Google is saving themselves and not directly getting from another site. Martijn.

I recommend you keep the title long as is and let google cut it based on the keywords searched. Editing those titles to a certain length and keep them making sense isn't scalable. long title tag = text gets cut off in serps, not worse for SEO but worse for CTR page heading and page title not matching won't hurt your SEO.
