Do your training in Germany and then work in Switzerland?

Hello,

I've now completed several internships and had good interviews. I can now decide whether to pursue an apprenticeship as an electrician for equipment and systems, a building materials tester, a bank clerk, or a chemical laboratory technician.
I am more or less interested in all types of training.
Now to my question: How can I work in Switzerland after completing my training so that I can earn more money? And which of the above-mentioned professions would be best for me to work in Switzerland?
