Learn Cloud or Do Oracle OCM ..confused

What would be more beneficial in the long term in your opinion?

Oracle OCM certification (and things learned during its time preparation ) or learning cloud .

I don’t want to do both as don’t get much free time and want to gain expert level knowledge so that I am gainfully employed for next 5 years or so .

I am oracle performance dba in my current role .

So looking for insights on what community members here think .

I am interested in both , but thinking what value OCM will hold with all the cloud focus these days . In my job I am getting chance to play with python , so atleast I am learning a new skill currently too.

Rgds,
