But - is there any advantage of using ext4 as opposed to, say, ext2? Especially on a flash storage medium, I would try to shy away from a journaling FS if I can. Please persuade me.
btrfs should detect if it's operating on a Flash-based device. From the feature list:

SSD (Flash storage) awareness (TRIM/Discard for reporting free blocks for reuse) and optimizations (e.g. avoiding unnecessary seek optimizations, sending writes in clusters, even if they are from unrelated files. This results in larger write operations and faster write throughput)

I've formatted my sdcard as btrfs. If it's good enough for Jolla's main storage, it's good enough for some music and stuff. As an added bonus, you don't need to partition the card, and you'll get btrfs' checksum validated reads - it's better to get an error than unwittingly reading corrupted data.
