I saw zerofree, but I’m not sure it would work on Ext4 or even work on

I don't understand the point of doing this.
Wes didn't say the reason he wanted to zero unused blocks, but I always
do this in kickstart scripts when constructing VM images as the image
size is considerably reduced by doing this...
