How exactly is the compression method set and how might one go about changing it?

If so would not explicitly applying the attribute let the file have the compression specified by BTRFS mount in which it resides (assuming forced compression is set on the mount)?

This sets the fsattribute but does not specify compression method. btrfs takes the method from the compress mount option (force-compress is not necessary). If compress isn't set in the mount options, zlib is the unfortunate default method.
