Efficiency of calorie acquisition is not the same as sustainability though. Culling an overpopulation of deer that keeps a forest from developing or an invasive species that is wreaking havoc on an ecosystem can both be a net positive on the ecosystem and in terms of sequestering carbon.
Meanwhile growing crops on former rainforest land is a clear net negative.
Those are edge cases though of course and with your average store selection, going with plant-based will just about always be more sustainable.
I would argue lab grown meat is fine, but afaik it is still more resources intensive to produce than, like, tofu. And it’s not like it’s going to be available in appreciable amounts in the near future.

meat is inherently the most inefficient way of consuming calories, let alone the pain, suffering and horror it causes.
there’s no morally or ethically correct way to eat meat, unless you’re an indigenous tribe that literally has no other option.
