Ask HN: What teckstack should I use as a noob?

Hi, I am a noob webdeveloper (only 2 projects behind my back). Question: I want to make a new "directory" site about a given niche with some new-wave visualizations (e.g. charts to visualize data), what techstack should I use in the era of AI assistants, IDEs, and easy-to-use Postgre providers? Also, do I always need a langin page (with a Hero), or should get to the point immediatelly? Thanks, Ben
