I may post too much on these things, and its all opinion, but I'm going to give you some Bend cons in your list since I can sing the praises all day long.
Live music--> I have had some fun here and there, but what you find here will be the 'biggest' touring bands you get. I had fun with some hardcore punk a few months back, but you're driving to Portland otherwise (a little over 3 hours). Most of Bend really shuts down early. Like 8-10 pm. So if you're still active in Austin's scene, you will miss that.
"wifi"-->depends on the speeds you want, but anything over 25-30mb you're looking at Bend Broadband which has a monopoly here and gets complaints all the time. They also are sneaky bastards who will up your bill while you're not paying attention. Then you get to call in and go through hell trying to get it back to what it was. I've only had one 'serious' outage that interrupted my work day, but I read all the time about other people having to deal with them. Austin had many more choices and options.
"cost"-->um, yeah. We got lucky and bought our home right as Covid was shutting everything down. I (and many) prefer the West side of Bend to the East side for various reasons. I am not surly elite so in just one year my home went up to where I wouldn't afford it now. In two years even more so. Groceries are definitely higher here, imo. And fuel, although not as bad as California in gas prices (but what is). No sales tax, though, which is wild when you experience it the first few times. And property taxes are more than reasonable. Personal Income tax though, so maybe that's all a wash, depending on your situation.
weather-->I love the four seasons. It's great. However, last summer for about a week the smoke from fires in Oregon and California got bad, and apparently this happens for at least a few days most years. Knock on wood hasn't happened yet this year. Last year, Christmas Day looked like we lived in a snow globe. My first White Christmas ever. Loved it.
The rest of your list, yeah, it's heaven.
