IMO it depends on the job. Open floor plans are good for ops roles and some front end roles where teams of people are engaged in substantially similar work driven, especially event driven work.

Lower density low cubes are ok. Offices are great for managers, PMs or professionals like attorneys, engineers or accountants.

From my perspective, remote works if the culture is friendly to remote or conditions like traffic make commuting a misery for everyone. As a manager of managers, we historically have had a lot of problems with remote employees compared with people in the office.
