Please add F2FS as an option in the installer
F2FS is the better filesystem option by far for NAND media used in sata ssd and m.2 nvme drives as it's fast and prolongs the life of the drive compared to Ext4, ZFS and btrfs
It's also fairly robust and not a brand new experimental filesystem, android devices have been using it for years already
the necessary support framework is available in the repositories upstream for debian and ubuntu already
