Accounting & Commerce

CA: One of the most common career options which crosses every commerce student's mind.
M.com: It is very common for students who want a masters degree in commerce after completing B.com

The primary goal post-qualification should be to gain as much experience as possible. Thereafter, courses can be pursued part-time or in an executive format.
Courses depend on where your interests lie and what you have already done. If you have done B.Com, it is advisable to pursue LLB. If you have already done an LLB, you can pursue the various courses offered by NISM Certifications, or BSE/NSE certifications.
Alternatively, you can go on a tangent and pursue LLM/MBA with some kind of corporate/financial specialization.
You always have the option to take advantage of the MoUs of ICSI and acquire memberships in CISI as well as ICSA.
I can suggest pursuing CA/CWA but won't recommend it as one can practice/be employed under both qualifications and hence if you work under one, the other is useless (it does look fancy on your CV but that's about all it can do).
