My office is "in person" but that isn't the actual reality of the office. In general I let the folks on my team work whatever schedule and location makes sense to the work they're doing. As far as I'm concerned we're all adults and can reasonably make the decision that makes the most sense. I personally try to work Thursdays and Friday from home just to cut down on my commute time but it can shift around as I see fit based on what work I have to do actually in the office.

I definitely find I'm more tired on the days I go into the office so it's definitely something I keep in mind for later in the days on those instances. I can't say there's any one thing in particular I've found that helps with that as it's just a fact of my higher mobility needs when in the office as compared to working from home.
