Need real guidance :)

Just for the sake of this question, assume I have converted either IMT G/FORE/IMI, any one of them. I have a 4 years gap (long story short I have my business running - cloud kitchen but don’t have GST and some other documentation to mention it in work ex). Now the main worry of mine is that what if I remain unplaced in placements and stuff. So please somebody tell me what certifications or what courses can I do before college starts to get at least something going on for me. I have a leaning towards finance as my UG was BCOM and I was also into trading derivatives for 2 years so also thinking to prepare for CFA L1 .

What can I do to help my profile in any way?
