Seeking Guidance: Choosing the Right Finance Sector

As I'm about to finish  my master's degree, I find myself undecided in the world of finance. With sectors like M&A, ECM, DCM, LevFin, Structured Finance, , , FP&A, Risk Management, FIG, Infrastructure, PE, VC, HF, etc (basically any) , the decision on where to specialize seems daunting. How do we truly know which sector aligns best with our skills, interests, and career aspirations? I can't take 1 year for each industry doing entry level internships, specially since in the beginning most of them is just powerpoint gruntwork, or else i'll be 40 by the time i come to a conclusion I'm keen to hear from seasoned professionals and fellow newcomers alike. How did you find your niche in the finance industry? What advice would you give to someone in my position, still exploring and yet to pinpoint their preferred sector? Any insights or personal experiences shared would be greatly appreciated as they could greatly aid in navigating this crucial phase of my career journey. Thank you!

Edit 1: even sectors like wealth management, right now , coming out of the masters almost every aspect of finance seems interesting to me in some way or another
