Rest Pause, drop sets all that stuff has a place. I wouldn't recommend them to novice lifters though.
Muscles adapt to stress, so changing the variables will help them grow. Can be as simple as adding weight or using other techniques as listed. Also using other lifts beyond the big compounds will never hurt once you have good handle on the big ones.
I personally like using bands or rest pause and partials on the final sets after failure.
You cannot be physically strong if you are mentally weak.
