This setup worked out for me to get a Garbaruk 11-50 cassette on my Q100CST Hub motor.

Other current 11-50T cassette options are OneUp and SunRace. I picked up the Garbaruk because it was the lightest at 300 grams.
Setup:
11-50T 11 cog Garbaruk cassette
X01 Eagle Rear Derailleur 12 gear
XX1 X-ACTUATION Trigger Shifter 11 gear
The reason it works is that the SRAM and Shimano 11 speed cassettes have almost identical cog spacing.
The SRAM 12 speed X01 derailleur has the same cable pull ratio as the SRAM 11 speed XX1 derailleur. This means you can interchange the X01 and XX1 derailleurs between the 11 and 12 gear drivetrains.
The X01 Eagle derailleur is necessary to make it up to the 50T cog, and it is designed to do so. One could also do the Garbaruk or OneUp Shimano 11 speed derailleur cage modifications. I decided to go with the SRAM Eagle X01 because it is originally designed to handle 10-50T without modification needed.
Then the XX1 shifter cable pull matches the cog spacing for the 11-50T 11 cog cassette when used with the SRAM X01 or XX1 Eagle derailleurs.
If you were modifying an XT or XTR derailleur with the Garbaruk or OneUp conversions, you would use a Shimano 11 speed shifter to match the Shimano derailleur.
I decided to buy the X01 Eagle derailleur because I did not yet have an 11 speed XT or XTR derailleur to work with. The SRAM XX1 shifter gives nicer shifting than my previous OneUped 10 gear drivetrain with RADed XTR derailleur.
I went with the SRAM XX1 11 speed chain. From what I read it is the closest locally available that is a bit thinner like the YBN 11 speed chain OneUp sells. The slightly thinner than 11 speed Shimano chains like SRAM or YBN work better to avoid backpedal downshifts on an 11-50T setup.
My guess on this setup proved right and I get excellent shifting with no backpedal chain drops.
