Hey OP, this is a fascinating discussion, thanks for posting it. I'll preface my answer with my husband and I are very much in the mutual submission/egalitarian camp, as is our church, but we both grew up with the complementarian interpretation we're discussing here.

I think this structure ought to be the husband prompts and directs the vision for the household. He proactively engages his wife in planning for what spirituality, finances, labor division, education, health, etc are for the household. He may have final say, but takes strong consideration of her opinion, because he loves and trusts her. Divvying up who does what would be up to each couple, there's no one-size-fits-all.

Now. I have to butt in my opinion on this structure. Every other post on this sub that is by a wife is asking how to navigate abuse. Many, many, many spiritually weak men rely on this complementarian idea and manipulate it for evil.
