> For me, the biggest downside of working from home is how easy it is to get distracted by non-work. I go grab a coffee and end up putting dishes away, cleaning up, etc.

Sometimes taking a short break like that is the best way to make progress on a difficult problem though. Realistically we probably get 2 or 3 hours of actual work done in a day. Everything else is a bonus and it comes and goes over time.
