Marketing site: mkdocs with static hosting like github+Netlify (unless it needs eyecandy, I don't do those). Buy a theme or build one.

Interactive sites: Django with server-side template rendering, very minimal Javascript, CSS via tailwind, bulma, or bootstrap. Buy themes if needed.

Payment, billing: send users to something like typeform+stripe, avoid building custom payment processing, order management, etc.

Web applications: things that need complex interaction in the browser I'd choose react.
