Suggest me a cloud skill

I have worked 3 years in Accenture in Sql for 1.5 yrs, Rest i moved to support projects where i don't have any future. Can anyone suggest, I want to transition to the cloud. But I am not sure which cloud skill has less technical work with good job calls/vacancies. I am ready to learn in any cloud like Azure, Aws, Gcp, Oracle.. Kindly please suggest me any skills which have good job vacancies/calls with less technical work. Thanks
