@threads317 Now I have no idea why
you were downvoted lol IMO you present an extremely rational, balanced approach to the whole question.
Unfortunately I was like you but had the same type of coparents, which made things unnecessarily adversarial and frustrating for 14 years. And as my children got older and started thinking and advocating for themselves, anytime they wanted something that went against what the other parents wanted, I was accused of manipulating them. (Projecting much...?)
It eventually got so bad that
when my daughter was turning 17 she had to literally run away to my house in order to be able to have a say in her schedule, (effectively eliminating one altogether,) because her dad was so rigid and strict about the schedule that he was unwilling to grant any flexibility even at her age. She lived with me full-time until going off to college, never stayed at his house again even overnight, barely saw her SM and him when she was home on vacation, and eventually went NC with him.
So there can be lasting consequences when our children become aware of the differences between approaches to the custody schedule.
