Generalist Developer Tips

I have a doubt on how to proceed to have a more Generalistic knowledge. I know that Generalistic X Specialist is a thing, but I would like some recommendations or tips on where/what to learn to become more of a generalistic worker. I have a background on Data Science (SQL, Python, PowerBI) and some experience in RPA with Python also. I dont know really what to pursue next, wondering Node.js but not sure. Have anyone with a faced this situation? And nowadays, what technologies would you guys recommend to be go more deep in this path? Thanks in advance!
