Also note, which I accidentally found when messing with filesystems Samsung created a filesystem called F2FS (https://en.wikipedia.org/wiki/F2FS) which apparently has been supported in the Linux kernel and GRUB for ages (2012 and 2019 respectively) and seemingly works great with any kind of flash storage (but mostly external flash storage, because why run F2FS if you can run BTRFS on your NVMe SSD :) )
Going to experiment with it a bit soon, because this IMO is a much nice format than thumb drives which stick out... yes you guessed it.
