For product design methods and collaborative exercises: https://www.aha.io You can use component libraries like skeleton UI:https://www.skeleton.dev/ or Schadcn: https://ui.shadcn.com/, so you don't have to design the components an style guides yourself. If you are interested in reading just one book and be confident about your design decisions, read : The User Experience Team of One by Leah Buley.

Came here to recommend the same book.

It is clearly written and rich in both resources and examples - does not hold back. An all in one education for UX design.
