re license)

Oracle Java and OpenJDK are practically the same code base.

Java <= 10 worked like:

paid Oracle Java - support almost forever
free Oracle Java - support N years
open source OpenJDK - support for N years

Java >=11 simplified that:

paid Oracle Java - support almost forever
open source OpenJDK - support for 0.5/N years

So you need to take OpenJDK if you don't want to pay.

And Eclipse works fine with OpenJDK.

re support)

Java <= 8 worked like:
* new version every 2-3 years
* all versions similar in support

Java >= 9 works like:

* new version every 6 months
* every third version is LTS (long term support)
* non-LTS versions are supported 6 months
* LTS versions are supported 3 years

If you are not interested in frequent upgrades you will
want to only take LTS versions.

So you will upgrade 8 -> 11 -> 14 -> 17 -> 20.

re JavaFX)

JavaFX status is a bit messy.

Java 6 & 7 : separate download
Java 8     : bundled with Oracle Java, no modules
Java 9, 10 : bundled with Oracle Java, modules
Java 11    : separate download

So for Java 11 you need to download JavaFX.
