The partman part of the installer is one of the more obtuse parts.

I reformatted it to make it easier for me to analyze.

You have -1 in several entries and I didn't think that was a valid
value there.

I didn't try your recipe but it was missing line continuing
backslashes and the -1 sizes seemed problematic. Instead here is a
copy of what works for me.

Try this recipe.
d-i partman-auto/expert_recipe string \
lvm-multi :: \
512 512 512 ext2 $primary{ } label{ boot } method{ format } format{ } use_filesystem{ } filesystem{ ext2 } mountpoint{ /boot } . \
4096 4096 4096 linux-swap $lvmok{ } method{ swap } format{ } . \
20480 20480 20480 ext4 $lvmok{ } method{ format } format{ } use_filesystem{ } filesystem{ ext4 } mountpoint{ / } . \
20480 20480 20480 ext4 $lvmok{ } method{ format } format{ } use_filesystem{ } filesystem{ ext4 } mountpoint{ /var } . \
64 64 64 ext4 $lvmok{ } method{ format } format{ } use_filesystem{ } filesystem{ ext4 } mountpoint{ /home } .
Since having a separate /usr isn't supported anymore I didn't include
it. Feel free to modify this to do so however.
I prefer to allocate a fixed size to /home and to keep other space
available in reserve for allocation to other partitions if needed.
With lvm this space may be allocated on the fly. Here is an example.
d-i partman-auto/expert_recipe string \
lvm-multi :: \
512 512 512 ext2 $primary{ } label{ boot } method{ format } format{ } use_filesystem{ } filesystem{ ext2 } mountpoint{ /boot } . \
4096 4096 4096 linux-swap $lvmok{ } method{ swap } format{ } . \
20480 20480 20480 ext4 $lvmok{ } method{ format } format{ } use_filesystem{ } filesystem{ ext4 } mountpoint{ / } . \
20480 20480 20480 ext4 $lvmok{ } method{ format } format{ } use_filesystem{ } filesystem{ ext4 } mountpoint{ /var } . \
40960 40960 40960 $lvmok{ } method{ format } format{ } use_filesystem{ } filesystem{ ext4 } mountpoint{ /home } .
64 64 64 ext4 $lvmok{ } method{ format } format{ } use_filesystem{ } filesystem{ ext4 } mountpoint{ /dummy } .
Then after the creation later I unmount /dummy and lvremove the
partition putting that disk space back into the free list. That space
would then be available later to increase the size of any partition
you wish.
