S/4HANA Cloud and On premise for Servive

Hi

I´m thinking to acquire the Learning Hub (LH) product to training myself in Service but I have doubt about which one choose because there are two training in differents LH packages:

There is one called S/4HANA Service or S4700 as part of LH Financial

The other one is called Implementing SAP S/4HANA Cloud – Service or S4C25 as part of LH S4HANA Cloud

So, I ask about the differences between them, aren´t they focus on the same? Which of them is the right one to choose?, and finally is not it an error to include a module such as S4700 in an LH financial when it has more commercial and logistics topics, even CRM than financial?

Thanks
