--Thanks for this. Very helpful  I was able to validate that the field available_objects.resource_type is the same as the metadata field learningResourceType in the manifest file. 
--Sharing my queries:

select internal_id, object_id, 
(xpath('/imscp:manifest/imscp:metadata/lom:lom/lom:educational/lom:learningResourceType/lom:value/text()', manifest::xml, ARRAY[ARRAY['lom', 'http://ltsc.ieee.org/xsd/LOM'],

from available_objects
where (xpath('/imscp:manifest/imscp:metadata/lom:lom/lom:educational/lom:learningResourceType/lom:value/text()', manifest::xml, ARRAY[ARRAY['lom', 'http://ltsc.ieee.org/xsd/LOM'],

or

Same as

from  available_objects
where (resource_type like '%Moving%' or resource_type like '%Sound%')
