What Memory Card Does the Canon R7 Use?
The Canon R7 has two memory card slots which support the ubiquitous SD cards. The types of SD card supported are SD/SDHC/SDXC and UHS-II. I recommend SDXC cards which are UHS-II. These are much faster than UHS-I and will hold more storage than SDHC.

The two card slots can be set up as an overflow for stills or as a backup for stills or video. As well as setting up to record stills to one and video the second.
How Much 4K Can the Canon R7 Record?
The R7 has no record time limit which is most welcome. So you can essentially record until you run out of power, or out of memory, or if the camera becomes overheated.
Canon state in their documentation that UHS-II high speed cards are recommended for 4K video recording and high speed continuous shooting.
And here are the record times possible on the R7:

Do bear in mind these are approximations for the storage capacities. Your actual record times can vary due to other factors like weather conditions, battery condition etc.
How Many Images Can The Canon R7 Write?
There are a few variables that determine how many images the Canon EOS R7 can write. For instance the R7 uses the LPE6NH battery which is rated to shoot up to 770 images using the LCD and 550 shots with the viewfinder (both at 23°C).
The Other Best Memory Cards for the Canon EOS R7
The SanDisk Extreme Pro range is one of my preferred brands for SD cards and they have yet to fail me in my (just over) 10 years as a professional wedding photographer.
But there are other brands producing SD cards that are just as good, if not better.
Sony for example and the Tough series are cards that should last many years of use.
The build quality is of particular note, built with what seems like one plastic case instead of two. The design looks like it will help it to take a good bit of use.
