Need Theme

I am new to wordpress and need help with a theme. I want my site to function as a blog and a website similar to https://www.traceybuyce.com/. I need a navigation bar that will feature all of my pages and subpages when you hover on the bar and also have a customizable header. I’m not great a code so I’m trying to find a theme that has these two things first off and I can then try to learn some code to edit colors, etc. Any help would be greatly appreciated!!!!
