If I want to learn a programming language in stages—basic, intermediate, advanced, and possibly proficient—how should different programming concepts and topics fit into each level? I'm looking for a practical way to organize what to study without treating the levels as rigid requirements.

Try not to focus too much on mastering a language in isolation. The more important goal is learning programming: breaking problems down, choosing suitable data structures, testing, debugging, and designing maintainable solutions. Once those skills are solid in one mainstream language, picking up another language is usually much faster. The topics you need will also depend on what you are building, so the progression will not be identical for everyone.
A useful distinction is understanding the language versus understanding its ecosystem. Beginners learn the core language features, while intermediate programmers become comfortable with the standard library and common tools. Advanced programmers may extend libraries, study source code, and make informed design decisions. Going further could mean learning how the compiler, runtime, or bytecode works, but that is specialized knowledge rather than a requirement for every programmer.
That makes sense. So the stages are more about depth and independence than about completing a fixed list of topics.
