I totally get it with the kids thing -- I have a young kid but he's in preschool so not a distraction.

I have a split commute like you and it works great for me.

My commute is awful so the 2 days a week I WFH are a huge reprieve; I don't have to wake up super early to beat the traffic.

It can be isolating and I do sometimes force myself to go outside. I think most people tend to work longer hours at home too and it's easy to do if you don't watch out there.

Upsides include being able to more easily run errands and stuff like being able to do laundry while working, etc.

I don't mind the in-person vs virtual meetings. If I am craving working around other people I take my laptop to a nearby coffee shop and work from there for a bit.
