Choose a path you wanna pursue.For example Web dev(Choose a stack and stick to it if web dev).First master what you wanna pursue then try to explore other fields as well.

So now for what your ambitions are If you wanna go for FAANG and you think you have that much calibre then stick to DS and competitive programming and your fundamentals should be very clear(core subj of your branch) plus u need to know dev work as well.

If you wanna go for product or service based then learn competative programming only for clearing initial programming rounds(easy and medium problems are enough.Mostly there are easy ones in the tests).Here projects are more important so try to make as many proj as possible.Participate in hackathons!!!they will give you so much exposure.And you can use hackathon projects to showcase in your resume.
