Is there a reason for a humanoid species to be 'biologically' matriarchal with females being slightly more dominant than the males?

Following my last question asked regarding oviparous humanoids, is there a way for evolution to 'regard' females as the more dominant gender without going down that road, forming a heavily matriarchal society in the near-modern day? Many thoughts I have had are inspired by female-dominated species in our own existence. Lionesses going out to hunt, while the males stay to look after the cubs. Female hyenas appearing more aggressive and often take leading roles. And lastly, male seahorses facing the chore of childbirth. Other hypothesis I have devised have had the females fighting over a male breeding pool in the species earlier times of existence, feeding in the last aspects I have described.

Basically, to sum up the questions:

• Could a humanoid species have this existence where the males are reduced to roles of childcare, leaving the females to appear more 'dominant' and aggressive physically and heavily psychologically, without going the base route of a fully oviparous species? This could be an aspect common to the world with a few species.

• Perhaps to support this, could there be a system of reproduction where the males have a sort of pouch where the female leaves their young to develop fruitfully, emulating a similar system to seahorses with a more marsupial vibe? This could leave the female with more free time to procure food through hunting and gathering in their more prehistoric periods.
