For how pre-industrial farmers worked, look to the Old Order Amish. They are not isolated family units, the community is the bedrock. The oldest settlements found suggest group cooperation was essential in the development of hominids.

To be clear, there's no discrepancy between "the larger community was essential" and "daily life revolved around the homestead and kinfolk groups". The former doesn't refute the latter. Indeed, I grew up amid the Amish, and both were true: their daily work was on their own farm or else they were helping their kin farm and their communities were very important to them. I suspect that's also the case with the other hominids you're referencing.

it wasn't nuclear families hunting together, it was all the warriors/hunters of the tribe or whatever. that was "going to the office" for them. i wonder how those who wanted to "hunt remotely" would fare in that environment?

That's one hell of a false equivalence.
