You're not in as bad of a position as you think. Your life isn't over and you're so far from pigeonholed right now 

First, your profile sounds like you'll be competitive for FT. While I'd say your profile is probably competitive in general, especially being an URM you should have some opportunities. I'd try to identify all of the diversity pipelines for the major firms and hit them up (especially for firms that don't recruit on-campus)

Second, even if you bomb FT recruiting for strategy consulting, there are worse places to be than B4 tech. I know plenty of people who exited to more interesting jobs after a year or two that aren't implementation driven

Third, worst case you can always just go get an MBA later if you're really unhappy

FYI, it's not really easier to get interviews with T2 firms if they don't recruit from your school -- sometimes it can be harder because they often have smaller class sizes so they can focus on their specific targets
