Trying to decide on a used Prius

Hello,
I'm hoping I can get some advice on purchasing a used Prius.
Our plan is to pay cash. We could go as high as $8000, but honestly, it's a little scary, as we've never spent that much on a car before, and we expect to need to replace our family car in the next 6-9 months as well, so we'd be more comfortable keeping it in the $4000-$6000 range. We'll be paying cash, looking on Craigslist and Facebook Marketplace.
This will be my husband's daily commuter, round trip driving about 75 miles per day. (So we're expecting to put ~18,000 miles per year on it, hoping to be able to keep it for at least 5 years.) He has been driving a 1992 Civic for the last 8 years.
We live in SW Washington state, halfway between Seattle and Portland. I've noticed, though, that some areas of the country have consistently lower prices, and so I'm considering going out of state - Austin / San Antonio area - to get one.
So, doing a bunch of reading here, it sounds like some people are more comfortable with a higher mileage, but newer car, than an older, but lower mileage car. Is that right?
Here are the options I'm seeing today:
A. Local, 2004, 123K miles for $4800 - One owner, private seller, has Carfax.

B. Texas, 2010 Prius Four, 111K miles for $7400 - small dealer that only does 2010 and later Prius - has Carfax, says he got it at a dealer auction, was probably a trade-in. Carfax shows 2 owners, water pump was replaced in May 2016

C.Local, 2011 - can't determine trim level - 133K miles, $7800. Private owner, looks like English isn't first language, so it makes me a bit less confident about being able to get accurate information from seller.

D. Texas, 2013 Prius Two, 102K, for $9400. Same dealer as B. Really more than we want to spend, but...if it were substantially better than our other options we could stretch to make it happen.

I'm super grateful for any advice.

 

Thanks so much for you kind and generous response!
So, I revised my search based on your recommendations, and found a 2007 - 132K miles, $5000, up in Issaquah. Private owner, doesn't say if he's the first owner, and doesn't mention a Carfax. I've sent a message to ask. So you'd recommend something like this over my Option B?

 

Actually, never mind, probably. That one in Issaquah suspiciously has the exact same wording in the listing as a different Prius listed in Seattle, by a supposedly different person. Hmmm....I don't trust it. I'm guessing this is actually a dealership.
