Welcome to Asciidoctor and thanks for the feedback.
You're correct that AsciidocFX is a editor / frontend for Asciidoctor. While we're excited about it's growth, you'll always get the best publishing experience using the Asciidoctor tools directly (esp as they continue to evolve themselves). That's true of any abstraction you introduce.
It's not a goal of Asciidoctor PDF to provide advanced layout capabilities, at least not right now. The goal is to give publishers enough control to apply a unique branding to the document. Based on the research we've conducted, this is what most people want.
If you need advanced layout capabilities when writing in AsciiDoc, you should continue to leverage the LaTeX toolchain for publishing by converting AsciiDoc to LaTeX. You can do so using the LaTeX converter, available at
https://github.com/asciidoctor/asciidoctor-latex.

I think you're confusing writing with publishing. I think it's safe to say most agree that writing in AsciiDoc is simpler than LaTeX. I'd be interested to see a side-by-side comparison that illustrates LaTeX as the simpler format.
Publishing is always difficult, no matter what format you write in. The Asciidoctor toolchain tries to ease this path by avoiding complicated or obtuse tools (like XSLT) and providing sane defaults, but it still requires talent to produce something that's both unique and professional. Over time, more templates will emerge that provide off-the-shelf solutions, but that comes at a trade-off of lacking uniqueness.
> What I could not find any information about is how to get hyphenation (in German) to work. An unhyphenated PDF would be an absolute no-go for me.
That's currently not implemented in Asciidoctor PDF, but it's both possible and planned. See
https://github.com/asciidoctor/asciidoctor-pdf/issues/20. If you need it sooner, and don't want to get into writing an extension, you can use the DocBook or LaTeX toolchains, which both support this feature. I recognize using these toolchains adds unnecessary complexity, which is why we're aiming for first-class support for hyphenation in Asciidoctor.
> Is there a way to influence the style of the index or the bibliography like in LaTeX?
In Asciidoctor PDF, not currently. If you want this feature and can describe the requirements, feel free to open an issue at
https://github.com/asciidoctor/asciidoctor-pdf/issues.
To reiterate what I said above, you can always just convert to LaTeX and use the LaTeX toolchain. That's the flexibility AsciiDoc affords you.
