Here is an advice centre of the City of Zurich (not sure where you're planning on moving to), about education, in English.

Here is the Viventa school, which offers young people living within the City of Zurich a kind of bridge year, to help them integrate into Swiss society (how the world ticks, here), learn German, and also to help them work out what to do next, onces their language skills are up-to-date.
https://www.stadt-zuerich.ch/ssd/de/...tegration.html Im Berufsvorbereitungsjahr Sprache und Integration bauen Sie Ihre Deutschkenntnisse aus und trainieren Kompetenzen für das Arbeitsleben. Sie lernen, Ihren Alltag in Zürich selbständig zu gestalten und bereiten sich auf eine Berufsausbildung vor. Ihre Lehrperson begleitet und unterstützt Sie bei der Lehr- oder Arbeitsstellensuche.
In the language and integration pre-vocational training year, you build up your German language skills and train competences for working life. You learn how to organise your everyday life in Zurich independently and prepare for vocational training. Your teacher will accompany and support you in your search for an apprenticeship or a job.
https://www.stadt-zuerich.ch/ssd/de/...asserelle.html Sie sind zwischen 15 und 21 Jahre alt, neu in Zürich und möchten sich auf eine Berufsausbildung vorbereiten. In der Passerelle lernen Sie Deutsch und Mathematik, setzen sich mit Ihrer Lebenssituation auseinander und lernen, sich im Schweizer Alltag zurechtzufinden.
You are between 15 and 21 years old, new to Zurich and would like to prepare for vocational training. In the Passerelle you will learn German and mathematics, come to terms with your living situation and learn how to find your way in everyday life in Switzerland. Some young people go from Viventa into the "Sekundarschule für Erwachsene" (this is the level of school that most people in Switzerland complete, before they leave school). Others, can move into a practial training (typically one year, low pay, part training on the job), and yet others into an apprenticeship.
Apprenticeships take 2, 3 or 4 years, depending on the field. The person absolutely has to have a fairly good command of German, to do this, because they go to school for 1 or 2 days per week, throughout that time, and work on the remaining days of the week.
The range of apprenticeships is very wide, from carpenter, electrician, and plumber (that one also knows in anglophone countries) but then also covering many other areas such as shop staff, nurse, hairdresser, painter, lab assistant, various kinds of techicians, glazier, confectioner, baker, and office clerk. All of these qualifications (and there are many more) are respected and considered a reasonable way to earn one's living. There is not automatic pressure, in Swiss society, to go to university: some do, some don't, and that's considered fine.
From there, a person who has completed their apprenticeship can then add on additional years or modules which will grant them permission to attend technical or business colleges, and in some cases, even universities.
For the purely academic stream, there is also the option of attending the "Maturitätschule für Erwachsene", which is a way for an adult to catch up on the university-entrance that they would have done, had they gone to Gymnasium school.

This is the Swiss handbook (in English) on apprenticeships, which sets out the framework. At the end, there are more links of information centres, etc.
