Hello, I know you're going to have a lot of bids so I'm going to make this quick.
I spent a lot of years learning web development and most of my time was spent on building original ideas with html/css and javascript. Since you're a youtuber that is looking to expand(congratulations btw!) it would be a good idea to keep things simple by adding a main section, a little bit about what you do, merch section. And most importantly a section where you could get ideas from fans. The "fan ideas" sections would really help you build a connection with your super fans who go into your website.
Would love to spend more time finding out new ideas, but without much context about what you do, I can't help but generalize.
Thank you for your time, and good luck with your channel!
