I've already learned Python and want to start studying data structures and algorithms. Should I continue with Python, or switch to C++ for better long-term growth? I'm also interested in becoming more fluent in the language I choose, so I'd appreciate advice about learning value, interviews, competitive programming, performance, and practical programming skills.

The core concepts are language-independent. Arrays, trees, graphs, sorting, searching, and complexity analysis work the same way in either language, so Python is perfectly fine for learning DSA. Focus on understanding the ideas rather than treating the language choice as the main issue.
C++ can be useful if you want to understand what is happening under the hood. You have to think more about pointers, memory allocation, object lifetimes, and implementation details, which can give you a stronger feel for how data structures work internally. The trade-off is that it takes longer to write and debug.
So both languages work, but C++ may be better for understanding the lower-level details?
A practical approach is to stay comfortable with both, but learn DSA in the language that matches your goals. Python is especially useful for AI and machine learning, while C++ is valuable for competitive programming, performance-focused software, and gaining a deeper understanding of memory and execution. The important thing is to learn complexity, problem-solving patterns, and implementation—not just memorize language syntax.
For interviews and general problem solving, Python is often the more convenient choice because the syntax is concise and the built-in tools let you focus on the algorithm. C++ is usually preferable for competitive programming or CPU-intensive problems, especially when input sizes are large and Python might run into time limits. C++ also has a strong standard library, so you do not have to implement everything manually.
C++ can be a good learning choice, but I would still use Python in an interview unless I was equally confident in both. Python is easier to read and less likely to make the implementation distract from the solution.
That makes sense, although I also want to become more fluent in whichever language I use.
