What after Java, Spring Boot, Angular ?

I have worked primarily as a Java Full Stack Developer in the same company for almost 4-5 years now. Being a full stack developer, I had exposure to working on other technologies like Angular, GraphQL, Docker, Jenkins, GitHub Actions, K8s, etc, as well.

Now I am looking for a switch in company. What are the things that I should focus on now?

Also, if anyone knows what salary is being offered to St. devs these days in Java Spring Boot ?
