Need advice on learning strategy

Hello! I started to learn programming like 5 years ago. Now I am somewhat similar to fullstack dev working more with backend part but ready to implement simple interfaces. I use python (flask, django mainly) and vanilla JS. Have like a couple of years of working experience now. The thing is, I doesn't know what to learn next. I do my tasks at my job right know, have no problems with finding solutions and information, but I understand that there are so many things I don't know and I cannot understand what to choose next career wise.

Especially this whole code generation situation and people saying that I maybe won't need to code anymore makes me think like should I even bother learning/practicing frameworks I don't know (FastAPI, for example, or some popular ORMs, or picking up JS framework to become more proficient in frontend part), or should I stick to fundamentals (algorithms, DB theory, CS in general), or maybe even picking some related skill (devops, security, QA).

Would be happy to get advice what you consider important to stay relevant in this job in the coming years. Thanks in advance.
