I would humbly suggest that you invest in a new imagination. I think if you took a poll of the top players (HoF, SG, GOTM, multi-player) what the best trait was, and could get honest answers, the vast majority would say Agricultural. The power of food and extra people is not to be denied. SirPleb's HoF Sid game, Moonsinger's HoF Sid game, my Sid Always War game, the two successful (to date) Sid SGs...they all have in common the Agricultural trait...and little else.
If you're talking pre-C3C days, I can see an argument that Industrious is the strongest. I think you'd get some disagreement, but at least there's a strong case there. With the downgrading of Industrious in C3C and the power of Agricultural, it's not close. Arguing Industrious as the second-most-powerful trait will find a lot of support (not me, personally, but I would definitely agree it's a very debateable issue). But #1? Not gonna happen.
I would suggest you build a lot more workers when not Industrious. Jungle starts? No problem. It's even easier with an Agricultural civ than with an Industrious one, simply because of the extra food, meaning extra population, meaning more workers easily. 3 non-industrious workers are as good as 2 Industrious and it's not impossible to adjust your thinking to just build a whole lot more workers when not Industrious. Some of us manage to do it just fine, regardless of the start.
