You can also get ext4 (with journalling) rather small so it's usable on an MCU.

Embedded File Systems - FatFS, LittleFS, SPIFFS?

Is there a standalone implementation of F2FS for MCUs? Something like lwext4?
Alternative to FAT for SD cards?

For MCUs the problem is more likely to be finding something sufficiently small to fit in flash. The linux kernel filesystem code is too big and depends on too many other parts of the kernel but there are embedded oriented implementations like https://github.com/gkostka/lwext4 (though I've never tried it)

Is it possible to rebuild a zipped LineageOS ROM with Apple emojis?

For the 4th step, you could use loopback devices: sudo losetup /dev/loop2 system.img and then mount it: mkdir system && sudo mount /dev/loop2 system. Only works on UN*X, though. Or, use ext2rd. It extracts ext2/ext3/ext4 disk images.
