Feedback on making navigation and hero sections responsive when managing a lot of content

I'm looking for different perspectives and ideas around making navigation and hero sections responsive when there is a ton of content to manage. The process is very time consuming. that part I do not mind. I want to get ideas from other developers' perspectives and see how they would tackle such a task. I would also be able to review my code and make sure I'm following proper standards. I attached an image to help provide detailed information about the navigation and hero section I'm referring to.
