Not MOOCs but college courses open to audit. Hands down the 3 introduction courses at UC Berkeley: CS61A, CS61B, CS61C. It's CS50 on steroids, spread across 3 courses. Tried a lot of things before finding those, nothing comes close.
1. Which versions of the courses did you do? I mean which semester versions. Can you link to them?
2. Why do you say nothing comes close? What is so special about them?
3. Did they make you confident as a programmer?
Because I tried a lot of courses and before finding this https://www.reddit.com/r/learnprogramming/comments/ortnef/a_..., it should be self explanatory.
Nope, they are just introductory courses, but they are good foundations to build upon.
