You probably leave it up to individual teams at the lowest reasonable level. Maybe there's a UI team that does a lot of whiteboard-based designing that chooses to be in the office certain days a week as a team. A different UI team prefers web-based design tooling so they agree to WFH. In some cases whole companies are fully onsite b/c of hardware requirements (e.g. Tesla) or fully remote (e.g. many smaller SaaS companies) based on what the company does. I honestly don't know what the long-term solution is outside of a lot of variation and individual/team/company choice. Within a given company any change should probably be gradual (e.g. start only hiring in geographic areas around your offices if you eventually want to go full/mostly onsite, offer to pay relocation to people who move close to an office). Senior execs love knee-jerk, emotional decisions to impress shareholders though so I doubt it will work out that way.
