Keep in mind commuting is not always about finding a base close to home. Try to get a base with more direct flights, better average seat availability, cheaper crash pads/hotels, and move up quick into line holder status. Commuting is easier and cheaper when you know your schedule.
I'm a DTW based, line holding CRJ captain, and live in SLC. Every week is pretty stable commuting and I can bid to come off my trips early on the last day to commute home. The DTW Delta terminal is probably the nicest in the country and easy to get through in a hurry.
Now if you stay on the ERJ, you can probably get SLC as an FO inside of a year after training.
