I need some career advice/help

I am currently a 3rd year accounting and finance university student. My plan it to get my CPAs then perhaps move into corporate dev when I'm in my 30s to have a family (I'm a girl). My last internship was at BDO with their Valuations-Advisory department. I just received an offer for a Research analyst role @ an advisory firm for high net worth individuals focused on alternative investments (~3B). From the interview, I've been told that I'll be supporting the team in ongoing monitoring and diligence of alternative investment funds, preparing presentation decks and writing research notes etc. The problem is BDO has just given me a return offer and now I'm debating if I should take the Research analyst role or return to BDO. Since my goal is to get my CPAs and eventually move into corporate finance/dev, should I take the new job or return?
