What are your MUST HAVE WordPress plugins (with reasons)

I just set up a WordPress site to serve as the blog Section of an ed-tech platform, and the first plugin I installed was yoast seo. I wanted to know if there are any other plugins you think might be useful for the success of the blog.

If you could explain the reasons behind your recommendations rather than just listing them out it’ll be really helpful for my decision process.

Thanks in advance.

Edit: I see a lot of people saying Rank Math so I’m going to give it a try
