Maybe one of the folks here can tell you if ABET matters - but given USC is ranked 3rd, likely easy to eliminate.
You have to be somewhere four years, day after day - and UT Austin is smack in the action - so if seeing the homeless constantly is going to be a bother to him, I’d think i’ts not the right environment.
That leaves one - where you noted " Penn State seems to have to most comprehensive and refined program in Architectural Engineering. They have beautiful, updated facilites and a 100% graduate employment rate for the last several years. The bachelor’s is a 5 year program and the masters adds on a semester or two."
So I think, assuming you can afford it, that’s the “safest” choice - unless he hates cold.
Good luck.
