I don't think it's a coincidence that a lot of stuff that gets left out falls under the heading of "women's work". There's an enormous blind spot that underlies most discussions of work where working 'at home' is disregarded as though it is the natural state of women and not worth mentioning.
Women have always worked full time. Out of the home, in the home, with their partners, with their villages. Read frontier biographies from the US western expansion and notice the partnership and shared responsibilities. Notice who takes the deer carcass and processes the meet and hide. Notice who churns and cans and turns fabrics and leather into clothes and shoes and hats and bedding.
It rarely gets discussed, and feeds into a mythology which treats women 'working' as something that started in 1970 and is a sad byproduct of economic necessity.
The hunting and gathering (and storing, and shelter, and guarding, and...) surely were as varied as semi-modern (pre globalization) societies. The amount of work would depend on the natural environment and climate, hunting or fishing, trade with other local tribes, culture and mythologies.
I'd argue that the few, highly sequestered, remaining hunter gatherer societies, by virtue of being the only ones still around, are likely to be very much outliers in some dimensions and actually plausibly quite different from our own ancestors.
Food preparation and preservation, shelter, crafting necessaries like eating implements, food storage vessels, clothing, and weapons - these keep a member of that society (except for some of the 'elites' of those societies, naturally) busy from dusk to dawn.
This persistent myth of the low effort required to subsist as a hunter gather needs to die.
