Leaving it off is totally the right call here. A decade of actual work experience completely overshadows a college GPA - employers care way more about what you've *done* since graduation than what your transcript looked like in 2014. Nobody's going to wonder if you're hiding something; they'll just see a professional with a solid track record, which is what matters.
The only time you'd want to include GPA at all is if you're pretty fresh out of school (like first job or two) and either don't have much work history yet or graduated with honors. After 10 years, it just clutters your resume and makes it look like you're reaching for credentials. Your actual job performance is your credibility now.
That said, if you're applying to something super competitive or academic-focused where they specifically ask for it, then include it. But for most positions? Clean it off and let your experience speak for itself. The fact that you're second-guessing this makes me think your work history is probably strong enough that you don't need it anyway.
