Which area pays more in Data Science field. Shift from a Statistical Programmer (SAS/R) role to a Data Scientist/MLE/AI

I am a Statistical Programmer (Clinical SAS Programmer, uses SAS/ R to analyze clinical trial/ healthcare data) with more than 5 years of experience and is interested to pursue a career in the Data Science (DS) field. With this interest I have pursued a course in DS, but now little confused to choose a specific area in Data Science filed as it is diverse. Can anyone suggest, 1. which area in DS field pays more and have a standard career growth 2. and their Job titles 3. and the company name. My priority is also to have better WLB, I will dig this into more once I get to know the above details. This information would also help me to understand the work they do and the areas to prepare for the interviews though the LinkedIn Job Description section. If you have any other ideas/suggestions to ease my search, please do let me know. Thank you.
