How to scrape website data without being blocked?

I'd like to ask everyone: what are some practical and less likely to be blocked website scraping methods and strategies? My focus includes proxy selection (residential/static/rotating), request frequency and concurrency control, request header/browser fingerprinting, CAPTCHA handling, retry strategies, and best practices for complying with robots.txt. Are there any recommended tools or vendors (for large-scale, stable scraping)? Thank you very much for sharing your experience and case studies!
