I live in an exurban town near a couple of small cities. I work remotely but am within 30 minutes of my office by car. And I'm within a 10-15 minute drive of grocery stores, (some) restaurants, and various big box stores like Walmart. It's not like I have quick access to big city amenities but I'm a reasonable pretty uncongested drive from most of the things I need day-to-day. (And I can walk but just for a fairly lengthy walk in the woods.)

The trouble comes when sprawl catches up to your exurban city. Now, one of two things happens: either your 15 minute city becomes a 30 minute city due to traffic congestion or zoning laws limit new construction and the cost of living there increases dramatically. If you managed to buy a home there, you'll be fine but renters soon have to seek either the next exurban spot or an older, decaying area closer to the central city.

We're talking an almost 500 year old farm town near a 80,000 person (twin) city so there isn't really a "central city" in the sense you're thinking of. They're old mill cities but there hasn't been a whole lot of sprawl over the past decades. It's pretty far out from the nearest major city.
