I ordered my R5 with
Canon BG-R10 Battery Grip,Canon Control Ring Mount Adapter EF-EOS R , and
Canon LP-E6NH Lithium-Ion Battery . With that said, i need to humbly ask a stupid question, and I hope people can help. I have been trying to figure out which SD card to buy. I know to look for a Compatible with UHS-II V60 or V90 for video. There are a number of designations (sdxc, SDXC2, XQD, ETC.), plus many manufacturers. Since this is a higher MP camera that I will likely use for some video, these decisions are new for me.
Thanks all.

There is a wide range of UHS-II SD cards available. Sandisk specify 300mb/s (UHS-I is only 170mb/s).
A much smaller range of CFexpress cards and Canon (to my knowledge) han't released qualified CFe cards for the minimum speed needed. Only the 1DXiii has a list and the R5 write speed should be similar to 5.5k/60
I have posted this before and happy to update if someone has new information/spec sheets
The Canon Website indicates that for RAW movie 5.5k60p Recording four CFExpress Cards are supported:
ProGrade Cobalt 325GB;
SanDisk Extreme Pro 512GB; and
Lexar 256 and 128 GB cards.

Max speed, size, avg speed
600MB/s Gold 120GB => Avg 145MB/s
1000MB/s Gold 256GB => 350MB/s
1000MB/s Gold 512GB-1T => 500MB/s
1400MB/s Cobalt 325GB => 1300MB/s
The avg to max speed difference is huge from 25% to 50% for gold but cobalt is pretty close to max.

64GB 800 MB/s
128/256GB 1200 MB/s
521GB 1400 MB/s
Lexar. I can't find a datasheet for them... only 64GB — 512GB Up to 1750MB/s read, up to 1000MB/s write.
If Lexar 128/256GB cards are okay for the 1DXiii (assumed) 1000MB/s then why aren't the Sandisk 128/256GB included?
Sony tough
128/256GB up to 1480MB/s
