To reduce the size of the initramfs and also to speed up the boot (by only decompressing the modules that are needed), please compress the kernel modules. From size and speed perspective, either use zstd or xz. I suggest to go with zstd -19.
This change is independent of the initramfs-tools version. Old initramfs-tools versions will decompress the kernel modules before putting them in the initramfs. New initramfs-tools versions will put the compressed kernel modules into an uncompressed cpio archive (see bug #2028567).
