In general I like your suggestions. However, I would suggest that all these objects give various combat buffs while fighting near the location of the banner/tapestry. Thus no increase for industrial production or farming.
Reason: Any village building those objects already has a good industrial production/farming going, otherwise they wouldn't be able to build them in the first place. Thus these objects give a village that already has plenty of production more production - and give a village that already has plenty of farming more farming.
