10 miles allows visiting every weekend, it becomes common for the whole extended family to meet for Sunday lunch as I see of my siblings. It also means if you need help moving, replacing a roof, or something else you can make a phone call and get plenty of help on a Saturday. My parents choose to live 30 miles from their parents - close enough to visit every weekend, but not so close they would poke their nose into the kids business every day.

I live 300 miles from where I grew up. Going to "back home" to visit is a big deal and so we don't do it often. Not only is two days lost in travel (technically it is 5-6 hours to drive, but it still wastes most of the day); we can't go home to our beds and so that means we need to get a hotel or sleep on floors - both have downsides. Thus we only consider this trip over long weekends. Visiting us is a similar effort for my siblings and so I rarely see them anymore. (don't get me started on visiting my in-laws who are over 1000 miles away - suffice to say we need a full week off to consider that)

In short, if you can do so I strongly recommend you live close to your friends and family and not move away. However there are many reasons why someone cannot do this.
