Plugins for WordPress

I know the answer to this question is irrelevant to the success of my business, and that I could simply google the answer. However, I’m struggling to find a plugin that looks aesthetically pleasing. I’m looking for two plugins for my WordPress site. One that allows my clients to share my blog post on their social media platforms (that doesn’t display the number of shares which for me is currently 0). The other plugin is a related posts/similar posts plugin. Any recommendations on which plugins you use or are able to recommend? Thanks a lot.
