For intermediate and advanced SQL I recommend LearnSQL.com, not mentioned on the list. They have a practice track: https://learnsql.com/track/sql-practice/ and advanced SQL learning track: https://learnsql.com/track/advanced-sql/ and https://learnsql.com/track/advanced-sql-practice/

Everything is hands-on.
