Possible migration with Make It In Germany?

Hey everyone, I hope everything is going well

I found this site while looking for the list of skilled shortage in the country, and I've been in communications with people from Arbeitsagentur.de and also completed (not very successfully) the language exam from the Goethe institute, so I was wondering…

1. Has anyone heard about the process?
2. As I've been working in a consulting company with SAP CPI, would that give me better chances?
3. Which city would be a better opportunity for a SAP CPI Integrator? (2 years of experience)
4. Would learning more modules improve my chances to get a better salary? (And how much could I ask for as of now?)
5. I also have some experience with machine learning and just got a certification, would it be possible/worth it to try and make a change?

Thank you very much for all the replies, I hope it doesn't bother anyone, I know and understand the migration problem in the country, but I just want a better opportunity in life.
