Pick anything and don't waste any more time in researching what to study. You know yourself better, what is your strong area and what is best for you.
Still, if you want to hear my suggestion then you can read the below.
Basic DSA is compulsory so don't skip it. I told this earlier in my tweets that whichever field you go, at least do 300 leetcode qsn.
It would take around 3 months to complete 300 leetcode questions, if you are seriously studying and not doing timepass anymore.
After that:
If your college offers good on-campus opportunities, continue sharpening your DSA skills and do CP till your desired rating.
But if you don't have on-campus placement then focus on Dev. There are plenty of startups that hire based on development skills. Build solid projects and use them to secure job.
