I think location and job stuff is far less relevant than people make it. Both cities have large employers - but yes, Phoenix is bigger.
ASU is far larger, has multiple campuses. I did my MBA there. It’s fine. For supply chain, it can’t be beat. They had more recruiters than students. Same for U of A and MIS.
My kid goes to Bama. Already interviewed 14 companies. Most are in the midwest - as he wants to be in manufacturing - and that’s where they are. Today, you have indeed and linkedin. Most companies that used to come, come on line. Yes, some still come. His first offer- never visited - so it’s a different world. All on zoom. He has had one company - fly him to Wisconsin.
So I think the worries about - job search, etc. today are unfounded to a large extent short of going to a specific name - like - your Ivies.
IU is very well thought of in business - yet it’s not a difficult admit for top kids. So it’s unusual that way. They place well. See attached.
I think - if you have time, you go visit. If you’re in TX, go see some schools - not just a big public but a smaller (Rice), an urban (Trinity), a mid sized school. Forget the names - figure out what she likes. If you look at big publics only, after visiting she may not be feeling it…and then it’s like - uh oh.
You might find a mid size like Denver (strong merit), SMU, Tulsa, Miami…or a small school. My daughter’s BF is at Denver - and has a ton of interviews - from a hospital company to Walgreens, Travelers, Nissan, Mars…and we live in Nashville…so again, I think the job thing is a bit unfounded. The healthcare company will be M&A and when I look at their glassdoor - they pay HUGE - and they just offered him the internship although no $$ yet (offer letter coming next week).
Why finance? Does she know what it is - it’s varied of course - from corporate to I Banking to other areas.
It really depends on cost desired - you can go to a Mizzou, a WVU, Ms State and so many more for cheap. Miami of Ohio, U of South Carolina…lots of good schools. You sound like a typical - I can afford anything - but I don’t want to afford anything. 
She’s a Junior - you have time - figure out if she likes big, medium, small. Urban, suburban, rural, etc. This way you can focus on putting her in the best environment for her - and then you can find budget from there.
A “great fit” on paper doesn’t mean a happy four years…so start visiting, even locally, to see the environment she might like.
