Greetings!
BTRFS wiki says there is no per-subvolume compression option [1].
At the same time next command allow me to set properties per-subvolume:
btrfs property set /volume compression zstd
Corresponding get command shows distinct properties for every subvolume.
Should wiki be updated?

What the wiki is talking about is per-subvolume mount options to control
compression (so, mounting individual subvolumes from the same volume
with different `compress=` or `compress-force=` mount options), which is
not currently supported.
You are correct though that properties can be used to achieve a similar
result (compressing differently for different subvolumes.
