Really you can generally just type in the brake you have an pull up the pads you need but these are going to be a good solid upgrade:
https://www.swissstop.ch/brakepads/d...isc27/disc-rs/
https://www.swissstop.ch/brakepads/d...c27/exotherm2/ (with cooling fins)
https://www.swissstop.ch/brakepads/d...isc27/organic/
and then for Kool Stop it would be the: KS-D640 or KS-D640S (I couldn't get a solid link to individual pads)
And one more set of options from Galfer:

You can also buy pads from Shimano in that same shape or from Tektro/TRP but I wouldn't go with Tektro pads their brakes are fine but I wasn't a fan of their pads.
