I'm using Sticky Posts on a current project to allow my client to "feature" a post for each category since they have content that remains essential for longer periods of time. I'm using the Category Sticky Post plugin here: https://tommcfarlin.com/category-sticky-post/ and it seems to work well, allowing for sticky designation within the Post and for the category at the same time. Only shortcoming is the lack of ability to make the post sticky for multiple categories at the same time.
