I have been using Next.JS for about 3 years now. It's very good for getting something quick together and is my main go to stack for PoC and smaller applications. If you were to start with web development Next.JS is a good way to start
I use Figma a fair amount in my day to day life. It's very beginner friendly but hard to master when it comes to design. I mainly use it for web design and can recommend it if you want to do a simple wireframe to a advance draft
