Without some design knowledge and experience (and dedication), starting from a blank canvas in Figma, Framer, or Penpot is going to be extremely difficult. Design is an art and skill in its own right.
Design software encourages/enforces good design rules through its interface. You couple that with a willingness to learn and a bit of practice and you can achieve some nice things. Especially given that the design of some types of websites is very codified like SaaS or blogs.
