On the topic of harem - this one is particularly well done as it is not a form of titillation for the reader but rather seems to be a logical side effect of the MC's OPness, which is yet to be fully explored (like the "perfect" statues of god being just a side note). I expect it to be either just physical perfection and exact symmetry (making him subconsciously the best possible mate) or perhaps god wanting to take things to the next level and planting him as a seed of achieving a more peaceful (and cross-bred) world.
Regardless Werebearguy is still incorrect here - this MC here subverts the tropes he listed: the MC is the most naive and dumb character in his tribe - a straightforward subversion; literally every female in the cast wants to have his babies and is totally into him for no reason at all - lampshaded to the point of absurdity.
As for the examples you've mentioned, I'd strongly disagree about Overlord. Harem is not just about fucking - it is also about being the center of affection. The MC is often oblivious to that existing or fumbles through resisting them urges. Overlord in particular has a three-piece harem already: Shaltear, Deadeye, Albedo being the mains but also Aura to some extent. This is bound to expand and the fact that the MC ignores his harem doesn't make it go away. As for female mc'd isekai - I agree they tend to be less haremy, but there's still reverse-harem aplenty - especially in otome-based ones.
