I've just finished testing 50 memory cards in the Sony A7 V, 23 CFexpress Type A and 27 UHS-II SD cards.

The A7 V isn't really pushing the cards that hard, so the vast majority of CFexpress Type A cards perform the same in-camera. The newer CFexpress 4.0 cards work just fine because the standard is backwards compatible with 2.0 devices, but there is no in-camera speed benefit to using them over a 2.0 card.
There is more of a variation in performance when it comes to UHS-II SD cards, especially the V60 rated cards. If you need to shoot to both slots at the same time, then you will always be restricted by the speed of the SD card, so it's best to go with a fast one!
If you plan to make use of the pre-capture feature a lot and shoot 30 fps, then this will eat into the buffer, so you'll probably be best going with a CFexpress Type A card to clear it as quickly as possible.
If you don't really shoot continuous bursts then a UHS-II V60 card is all you really need, unless you need faster transfer rates to your computer or want to record video in a mode that requires a V90 SD card or VPG200 rated CFexpress card.
It would be good to hear what cards people here are using, and if you've experienced any issues with them.
Tested in Camera: The Best Sony A7 V Memory Cards - Alpha Shooters
In this article, I put 50 memory cards to the test in the 33-megapixel full-frame Sony A7 V, measuring real-world in-camera performance versus the label speeds. In case you are unaware, the Sony A7 V features two memory card slots. Slot one is a dual slot that is compatible with the CFexpress...
