Here in Italy we discuss #2 - For example for an annual income of 30.000€ before taxes, it will be around 1.400 - 1.500€ month after taxes.

And I had the same experience: it's almost impossible to have salaries jump without changing jobs (and from a business perspective the reasons for that are quite obvious)

In your example, €30000 would be your RAL so #3, not #2.
