My biggest ones are revolved around finances, like starting a business together, getting a house, bankrolling dates, vacations, housing, etc. Mostly not intertwining our lives to where it would be difficult to have a clean break. Having a child together is another great example.
The "more petty" examples are personal things that test my patience. I have infinitely more patience for my spouse because they've at least demonstrated a capacity for change when I express concern/annoyance.
Periods of lesser communication. Being left "on read" doesn't bother me when I'm coming home to them later and we're aware of our schedules.
Curious to see what your boundaries are!
Edit-
However you want to interpret a committed long term relationship over something less committed. The terminology is creating quite a stir from both sides, tbh, and I'm not trying to invalidate anyone's preferred way of commitment.
I'm much more interested in how people navigate a relationship where they are "all in."
