To be clear, I understand your point and it's a good one: there are important factors far outside the realm of "consumer choice". Private companies promote the notion of individual responsibility for the environment precisely to shift attention away from their much larger, profit-driven production modes. But I can actual answer some of those questions, so I think we should tweak them to contradict my actions.

Point me to the shopping aisle that doesn’t wrap every sale item in plastic.

Produce and the bulk section. I also got a frozen veggie sausage box the other day that ended up being just sausages in a cardboard box.

Show me the power grid that isn’t energized with coal-electricity.

It depends on how you define grid but there are states that rely mostly on hydro or nuclear and fill "gaps" with natural gas.

If you're rich enough ("middle class"), you can buy solar panels / wind turbines for your house. This is obviously unavailable to most.

Motion me towards the long-distance travel solution that doesn’t spew green house gas into the air.

Technically there's no production of any kind that doesn't. Labor does this just from breathing. Cycling or riding a horse still have this problem, naturally. My answer here is weak, though.
