What is a good NanoVNA to buy for do antenna reading like SWR, VF and Length of coax cable type work. Also, location of short in the coax..

Any of them. The ones with a bigger display are easier to read.
But all of them can do what you’re looking for.
The other thing to look at is frequency range, some have a wider frequency range on the top end.
And connectors and cases - The originals have SMA connectors, some new versions have N connectors and a beefier case. (Which does cost something). I use 6” SMA-UHF and SMA-N jumpers rather than adapters, so the coax doesn’t snap the connector off the NanoVNA.

My Suggestion is
Do your research. you want a device based on the Open Firmware, you want a device that supports the software on GitHub.
Most of the devices are made in China.
The prices are all over the map, research down to who actually manufactures the device.
This takes time, but with internet access you can find and drill down to find what you want and are willing to accept.
OR
Purchase one from Amazon with a return ability. Amazon is good this way. while this is slightly more expensive but gives you time with the actual device to decide to keep or return.

If your main application is for ham band use, from HF to VHF/UHF (440MHz), save some money and get the H4.
If you need good accuracy on bands above the 440MHz band, and above 1GHz, I would choose one of the 'liteVNA' or V2 models with extended frequency coverage on the high end.

any of the nanovna v2 models .. or litevna 62/64
