Is there a close[dot]city but for Europe?
https://close.city/ is a really cool interactive map where you can select multiple different destination types (supermarkets, transit stops, gyms, etc.) and it shows you places that take the least amount of time to walk, bike, and/or take transit to the farthest destination type. But it is only for towns in the US. Have you seen a website like this for Europe or for the whole world?
