I specifically searched my last flat to be in a 10-20 min walking distance from the work location. Are there research results that compare the different modes of transportation? I would expect a sorting of (better) walking <= public transport <= driving yourself (worse). Or is the stress level the same for either?

Also was there a result in regards to the minimum distance necessary to the job location? While working from home has its own benefits, I would expect a certain distance between job and home to be good. My daily walking also helped with getting in the mood and with shutting down my work-mind.
