The Domain/Arboretum is between those suburbs and the city and it's a booming area these days with a lot going on. My advice would be to look near there or south of there for your housing. This gives you good commute flexibility for jobs in the burbs and the city, and makes getting into the city much more pleasant.
Traffic going North/South is getting really bad, so if you are wanting to be central/downtown during the weeknights you're going to want to stick around for a while and delay your commute or somehow offset your commute.
I have a coworker who lives in cedar park (our office is by UT) and fortunately for him his manager allows him to come in around 10 and leave at 4 to miss the traffic, but he has to make up for hours later in the evening.
Also, diversity sometimes looks like places other people love and you don't care for.
No public transportation means no public transportation that smells like urine. Since housing is so cheap everyone has nice cars.
Anecdotal example: when we lived in Tel Aviv (bad transit, although probably not as bad as many places in the US) I had several jobs and it would take me 50-60 minutes to get from home to work or vice versa.
This was not just me but is usual in greater Tel Aviv, unless you can afford to live in the city (almost nobody with kids does, metro tel aviv has 3.7m residents vs 450k for the city itself).
We've lived in Vienna before we moved and moved to Berlin after, both cities with great transit (that sometimes smell like piss). Both metros are comparable in size to TLV (metro Vienna 2.6m, metro Berlin 4.5m) and I've had several jobs in either - it usually takes 30-40 minutes to get to work and again it's not just me but the common case.
The problem is there is a culture of driving in Austin and not of taking the public options. Most people don't even know what is out there. We could do with quite a few less cars on the road.
Thankfully the climate is outstanding so I don't even need A/C.
