Create a clean Figma concept for my product landing page

I need a simple but nice-looking landing page design in Figma for my little product. I already know the basic content, but I want help turning it into something that feels modern, trustworthy, and easy to understand. The scope is just one main page, with a few sections and mobile-friendly layout ideas. No need for a big brand book, just a thoughtful design and a usable file I can build from later.
