Get the vocabulary right on Refactoring Guru
The reference catalogue for design patterns and code smells, with examples across languages and diagrams that actually read. Goal of this stop: being able to say what separates a singleton from a factory from an observer, not reciting three names.
Resource: refactoring.guru The site covers SOLID too, so both halves of the subject sit in one place. Do not read it all. Take the three patterns already living in your codebase and read those to the end. A catalogue skimmed leaves nothing behind.
