Recommendation for website landing page templates references?

I just started self learning web dev (front-end development) and wanted to build my own website, starting with a landing page. The company is about providing engineering / consulting services to clients. I wanted to practice my skills and also try to build something useful.

I was wondering if people can recommend me some popular repository for free (or paid if it is really worth) landing page templates I can grab the HTML / CSS / React codes for so I can tweak and start from there?

I will probably take the HTML CSS code and turn it into React as I am learning ReactJS at the moment. Any other beginner comments are also welcome! Looking forward to it.
