More examples for using StaticQuery/useStaticQuery as a datasource for parsing & using in other components

[NetLancer]

I've been searching examples/documentations a lot for using queries as datasource but ended up with scarce mentionings of the topic. There's only one i came across in gatsby docs and it is a simple example of siteMetadata query data sourcing. Here my case is a need for complex data which includes: node.frontmatter.{stuff}, node.fields.{stuff} and it all in several languages, so then i can import that complex data object and filter out with language argument provided. So i'm still struggling.. And which of the two ( StaticQuery || useStaticQuery) is more suitable and/or preferable for this sort of usage.

This is more of a feature implementation question, i'm building a multilang site/blog but have custom directory/file structure and so have to implement few thing without popular gatsby pluging. Pardon me if this is not exactly the right place to ask like this, but i really think it would be of much benefit to have those details in docs. Thanx a lot
