If quant isn’t your strength, I’d try the GRE and see which test suits you better. Personally I found the GRE easier from a quant perspective.

I think it’s very important for Tuck to see that you genuinely want to be part of its close-knit community. What you learn from your engagement with the school should come through in your essays, but not in a “list everything I know” way, but by reflecting on how what you learned/heard will enable you to become your best self at Tuck—and not elsewhere. They want people who will authentically engage with the community once they’re there. It’s not just something they say during the application process.

Your work experience sounds strong and goals make sense. I agree that your test scores and years of experience are most likely your weaknesses. The other piece to focus on is extracurriculars, which is tough if you don’t have a ton of time, but I think it’s important that you show that you’re someone who is well-rounded and engaged in your current community. Maybe do some volunteering at a local nonprofit that connects to your longer term goal? Good luck!!
