Which memory card for the Canon R50

Buy a 128GB V30 UHS-I SD card for the Canon R50. The SanDisk Extreme PRO fits that description. Canon lists the R50's single slot as UHS-I compatible, and a V30 card keeps up with the camera's 4K 30p.
Why not a faster card
The R50's slot is the limit. A UHS-II card has an extra row of contacts for higher speed, and a UHS-I slot does not use them, so the card drops to UHS-I speed. You would pay for performance the camera cannot reach.
The R50 also tops out at 4K 30p, with no 4K 60p mode, so it never asks for the sustained writes that push other cameras into V60 territory.
If you think you might move to a Canon R10 or an R7 soon, those bodies do use UHS-II, and buying a faster card now could make sense. Otherwise it is money better spent on a lens.
How big
128GB is the sensible size for most people. Photos take up little of it. Long 4K clips are what fill a card, so if you record talks or long events, buy a second 128GB card rather than one enormous one. With one slot and no backup, a card that holds a whole event is a card that can lose a whole event.
Bursts of photos
The R50 shoots 12 frames per second using an electronic first curtain. Canon's specification shows it does not have a fully mechanical burst. Long bursts fill the camera's memory and then wait on the card, and a slower card makes that wait longer. A V30 card is a reasonable match for casual burst shooting.
Batteries
The R50 uses the Canon LP-E17. It is a small battery, so a spare is worth buying alongside your card.

Before you buy
Look for the V30 mark and the SD logo on the card. Ask the seller to confirm where the stock comes from, since fake SD cards do exist. Then try it in your camera and confirm it formats and records.

Questions
Do I need a UHS-II card for the Canon R50?
No. Canon lists the R50's slot as UHS-I compatible, so a UHS-II card would run at UHS-I speed.
How many cards should I buy?
Two if you can. The R50 has a single slot, so a second card is your only protection if the first one fails.
