I've lived in different places here, currently I have a couple of options in a 400m radius, in my previous house I used to have two options in a 100m radius. Before that I lived in another country and had a small market at around 600m and the nearest supermarket was at 1.5km, I almost never went to the big one and instead had them deliver to my house, but it wasn't a chore going there, it was just boring and a waste of time when I could just order online.
A few years back I used to live in a small city and my options were 1km for a small market or 3km for a big one, you sort of get used to going the 3km to the big one when needed, but it's not fun, and I would consistently put out going to the big one until it was absolutely necessary. I believe 3km is bike distance, sure you can walk that much, it's not that far away, but it takes a long time and is exhausting carrying lots of groceries in summer for that long.
All of that being said, I was not born in Europe, so locals might have different opinions, although I think everyone I've talked to thinks that above 1km it becomes bike/scooter distance for routine things (you don't need a bike if you're going to the cinema at 1km, but grocery or other routine stuff it's worth the investment just on the time you'll save)
