What should I do?

So I am currently working on mainly Python and SQL. I was thinking of upskilling but I am confused whether I should go full stack role maybe learn react or should I go data engineer role and learn big data. I have worked with ETL software’s such as snowflake and Databricks.

I want to switch job but looks like no one is hiring for someone who only knows python and sql.(though major work is on sql only ) Any suggestions
