^This is some good advice right here. I'll add a bit more to this. If you can afford it, don't commute to your regional job. The QOL improvement in my opinion will far outweigh the (sometimes) lower paycheck that comes with this option.
Another suggestion. What you need to know is how soon can you hold PHX as an FO,
and how quickly can you can hold PHX
as captain. The second part often gets overlooked.

It's one of the most senior bases for both FO and CA.
I don't know how up to date that table is, but if accurate you'd need 1 year of seniority to hold PHX/FO, and a whopping 6 years to hold it as CA. That's a deal breaker in my mind if my goal is to avoid commuting.
It would be worth verifying that information via the forum. That information is also subject to change (for better or worse) if SKW changes how PHX is staffed.
Your ideal no-commute regional needs to have PHX be junior in both FO and CA seats. That way you can get in, fly, upgrade, and move on hopefully before the base seniority changes for the worse.
