From my past experience 50% of the time was sort of the magic amount of time to be in the office. Seemed the best blend of focus time at home and in person time in the office. Now I'm 100% remote but next job I'd look for 50 /50 mix.
I might consider coming into the office a few days a week if it's within reasonable walking distance, but that usually means living downtown which is usually a cost that exceeds the regional CoL compensation adjustments that most companies make, which means it's coming out of my pocket to be possible, and I am not going to commute unless it's East Asia style train commuting during off-peak hours, where I can actually do something while in transit.
Having an all-remote team with people who can work well remotely is a wonderful thing. It's rare to get a department full of people who can work well remotely, though.
I personally prefer companies that remove the people who can't handle remote work, but so many companies hired large numbers of unprepared people into remote jobs under unprepared managers in the past 3 years. You really have to be careful about team selection to build a fully functional remote team, but that wasn't happening during the hiring rush.
My observation is that with some people, I can drive to the office, find parking, find the people I'm meeting with, we go find an open room which takes time... sit down, bring up the laptop on the tv in the room....
I tell them the same fucking thing I told them yesterday on the webex.
They smile and nod and now they get it. Because I had to spend a fucking hour coming in to talk to them.
And then I've wasted half my damn day so someone who couldn't pay attention to me on webex felt compelled to pay attention to me sitting in a stinky room in a filthy chair.
Being able to see people face time face gives a different dynamic you cannot replicate with video calls.
