Please have your fiancé research what sort of educational opportunities would be available to you. Qualifications are even more important here than in the US, those pieces of paper matter.
I'm suggesting getting your fiance involved because you lack the language skills to do so yourself at the moment; while you will have to pick up German quickly, for now your fiance is your network.
Good to hear that you are learning German, but may I ask, why not Standard German first? Swiss German is not a written language (well, not formally), you will need good written Standard German for any job.
Do not underestimate the value placed on language skills - here it is normal to speak two, three, four languages. Employers will expect it. Don't fall for the myth that you can get by in English... the few who can are highly skilled expats in top jobs. Without other qualifications you MUST have good language skills.
So plan on taking an intensive language course as soon as you arrive. And not just any class, take one that works towards CEFR certificates. With language skills in your pocket, you have many more options.

But with no qualifications, no skills, no experience and no language ... your options really are limited to cleaning work or similar. To give you an idea - I require that my dog sitter to speak functional German. Without German, how could you possibly handle an emergency, which is a primary responsibility of the job? Many who hire child care would expect a similar level of language proficiency as well. Again, language facility to the point where you can communicate will be necessary.
But the good news is such jobs, when legit, tend to pay better than in the US. Just don't get caught up working illegally, meaning under the table, that's where low-skilled workers end up getting exploited.
But really - think about further education. After you have reached B2 in German, look into whether you'd qualify for apprenticeship programs. You are still young. Without formal qualifications you will continually face barriers.
So the real question: What sorts of jobs have you done already, and what do you want to do with your life? What would your career options, career path have been back home? The answer is how to translate that into a Swiss context. If you give us a bit more information, we could better help you.
All the best to you.
