Learn PLC. Where do you study? Is it difficult? Is it easy to find a job?
I do related work, so I have the right to speak. PLC is easy to use, and the typical brands are Siemens, Schneider, AB, Mitsubishi and Omron. It is suggested to start with Siemens, because there are many learning materials on the Internet, and S7-300 series will do. Whether you can find a job depends on whether you study well or not. You can find a better job step by step by studying and participating in projects.
