How to create different sections on my website?

Hi

I am using the Iconic one theme for my website (https://thewisdompearls.com)

I am using the Pages feature to create the different menus besides the HOME page. But I wanted to somehow do the following:

(a) Have a static landing home page for (https://thewisdompearls.com)
Currently it shows all the blog posts as per the published date.
Maybe have a slide show or just an image or some kind of media or a HTML code.

(b) Secondly, I wanted to have different sections (or pages/menus you might say) on my website. So ideally it should look like:
– HOME (a static page)
– PROJECT MANAGEMENT (all the blog posts relevant to project management should appear only there and nowhere else)
– SUPPLY CHAIN MANAGEMENT (all the blog posts relevant to supply chain management should appear only there and nowhere else)
– SOCIAL MEDIA (all the blog posts relevant to social media should appear only there and nowhere else)
– PMP EXAM RESOURCES (all the posts relevant to the PMP exam material downloads should appear only there and nowhere else)
– ABOUT ME (my personal bio and nothing else)
– YOUR ACCOUNT (a page for visitors to register/login to their accounts)

I tried using the Pages/Menus options, but either I am using it incorrectly or I am not too sure how to do this.

Any easy, step-by-step approach to do this? Or would this be too complex?

Thanks
