The model needs four buckets:

20-30: Needs mentorship, can live closer to the office

30-40: Has young kids, moved to the burbs

40+ AND Management: Developed management approach pre-pandemic, pre-Slack

40+ but IC: Could go either way

This is still HUGELY simplified, and please do not take offense if you are e.g. 30-40 without wanting kids. But "young kids" is just a huge difference in terms of the morning schedule and flexibility needs, especially as most families near urban areas have both parents working.
