There are many options, and, as others have said, working with a professional probably would be your best bet.
Newton is a remarkable surburban city, and, thanks to the Mass Turnpike, makes commuting into the city very easy, especially off hours. Also, the presence of the commuter rail makes it handy to get to Boston using the public transit. This is definitely a progressive, family-oriented suburb well worth checking out. Maria, a regular contributor and Newton pro, has kindly put in a plug for her distinguished city.
There are, though, many other options. For yourself, do realize that you can directly check out traffic live in the Greater Boston area, and see for yourself at various times what the commute may be like. I've included the smartraveler link for this below.
Also, mbta.com provides schedules, to give you a sense of commuting times on the commuter rail, buses, and subways, including from the suburbs. Its nice, especially in bad weather, to have backup options for travel, even if you otherwise would use your car.
Note, incidentally, that Boston has some quirks in terms of naming some of its neighborhoods as if they are separate cities. So, to clarify, "Boston Proper" is the term for the smaller area that consists of these neighborhoods. There are other nearby towns, such as Brookline or Chelsea, that may look like they are part of Boston on a map, but are separate municipal entities. "Greater Boston" is the term that includes a number of suburbs in the area.
Good luck with the search, and hopefully one of these pros can help you find a delightful new cubbyhole in the area for you to call home.
