Welcome to CodeRanch Mario and congratulations on achieving that score.
When you get a few moments you add yourself to

You mentioned that you were thinking on taking the Java OCP 809 exam.
I suggest that you take a few moments and read some of the stories found here
https://coderanch.com/wiki/659976/Ocpjp-Wall-Fame.
By reading the stories you can see what resources others used and how they prepared. This could save you time, money and frustration.
As for what else to be certified in, well that is kind of tough to answer. Not all employers treat certifications the same. Some employers do not even care about certifications.
The question
you should ask yourself is why are you getting certified?
If you are planning on exploring Android development then you may want to learning Kotlin
https://kotlinlang.org/.
It's been predicted that many Android development jobs and shops will soon be favoring Kotlin over Java for Android development in the next year or two.
Once you are Java 809 OCP certified you may want to look at the
J2EE certification path,
You may want to look into Oracle Database or some other database certification. Much of today's world uses databases for nearly everything.
You may also want to look into learning Java 9 which was released September 2017.
While there are no certifications for it yet, companies are and will start adopting Java 9 now or in the next few months.
