Could we extend https://documentation.magnolia-cms.com/display/DOCS62/Multi+field with information on how each multi field type saves the data? Without it, just the names are not self-explanatory enough to know which one to choose.

Technically, the most important one is the JCR multi-value field as this one saves data like in M5. People are looking for it, but they do not know they need to use this one and are using the first JCR multi field instead, which saves data differently.

The usual workflow of a person looking for which field type to use is:
1. https://documentation.magnolia-cms.com/display/DOCS62/List+of+fields
2. They see the multi field and then go to:
3. https://documentation.magnolia-cms.com/display/DOCS62/Multi+field
4. They try the JCR multi field, and it's not what they want and they write to us.
