If I am satisfied with my disk speed, why would I want to use system memory? What are the specific use cases where this is warranted?

Technically it'll have some impact on the number of write cycles your disk goes through, and marginally reduce the level of wear.

Most disks have a lot of write cycles available that you'll be fine anyway, but it's a tiny benefit.

Computers like a Raspberry Pi, where the OS is on a sdcard, will hugely benefit.

Yup. There's lots of advice about how to reduce cycle count, increase lifetime of sd cards out there. This post has a bunch of ideas, and tmpfs is definitely on the list. https://raspberrypi.stackexchange.com/a/186/32611
