Welcome to complex world of Medium Format Digital ... here's a little tutorial to help out:
The CFV backs only come in a V mount for use on the 500 and 200 series Hasselblads.
All of the 22 meg 645 type backs feature the same 9 micron pixel pitch as the CFV/16. The crop factor of these backs is 1.1X ... the same as the 39 meg and 50 meg digital backs.
Among the Hasselblad branded backs there are also the
CF and CFH versions, besides the previous Imacon Ixpress backs mentioned above.
The Imacon Ixpress 132C and 528C are both 22 meg backs, but the 528c is a single shot/multi-shot version with an additional 4 Res module suitable for static subjects. Be aware that the iXpress backs must be used with a separate 40 gig Image Bank-I ... which both powers the back and stores the images shot. These Image banks are long discontinued and becoming a little harder to replace ... and because they are basically Hard Drives, they will eventually fail and need replacing.
Note: They cannot be replaced by the Image Bank-II used for later model Hasselblad cameras. Here is what the Ixpress system looks like:

CFs were the next step from the iXpress 132/528. Instead of an Image Bank, the CF backs use a clip-on Sony L type battery for power and captured to a CF card (thus the name CF)... just like the CFV does. It differs from the CFV in that the color matches the H camera, and the camera mount can be changed using an iAdapter system that allows the back to be used on a number of different medium format cameras. These backs are discontinued, but information is still available on them ... ignore the price on the following page: (there are not many of the CF/22s for sale used because they never made many of them):

The CFH is another option but differs in that it only fits the H2 camera, and does not use an exterior battery, instead it is powered by the camera's grip battery. From the H2 onwards, Hasselblad changed the grip battery to a more powerful one so it could power both the camera and the digital back. Hasselblad would update a Hi to use the new H2 battery. A CFH/22 back can be had for about $3,000. to $3,500.

Unlike the CF and CFH 22 backs, the 22 meg 9 micron
Leaf Aptus-II 5. is still being offer new. I believe the Aptus-II 5 retail is $9,000.new, so if a used one could be located with an H mount it could be pretty reasonably priced. The Leaf backs are actually (subjectively) better than the Hasselblad CF or CFHs because they use the Dalsa sensor, which is renowned for excellent skin tones. They also offer a much larger LCD screen, and can be shot in ISO 50 to 800 ... ad the ISO 800 is actually pretty good. The only draw back is they only come in black.

Phase One also makes H mount backs, and I believe the H mount version's color matches the H camera grey. The P25 and P25+ is the 22 meg one and generally is available used and work on both the H1 and H2 (and now the H4X). The Phase One back married to a H1 or H2 is the most prolific and most used combination of camera/digital back used around the world. They differ from both the CF backs and the Leaf backs in that their battery is not clipped onto the bottom of the back, but instead fits with-in the back. These are extremely good digital backs and often are priced higher than others.

Happy reading ... LOL!

BTW, to get the same basic look and feel of the Canon 85/1.2L the Hasselblad AF lens you want is the HC100/2.2 ... it is roughly the same FOV and as a 80mm in 35mm terms, and f/2.2 is extremely fast for a medium format lens to provide subject separation from the background.
