google is known to show search results specific to search query. for certain queries, video results are preferred, for example anything involving showing of steps/tutorial/process. such queries will benefit from having a well optimized YT listing. we tried it and it has worked well.
another thing we used to do was to have a blog post for the same search query and embed that video into the blog and then link this blog post back from the video description on YT.
use structured data for video extensively for technical SEO:
