There is a set of application queries to get IFC properties and their values from library parts, search for Tags and categories on this page: https://gdl.graphisoft.com/reference-guide/application-query-options/
You can check the usage of this queries in “Tags and categories label” in ARCHICAD19. I hope it helps.
By the way I think IFC properties should not control objects parameters, as if the user changes anything in the IFC values, parameter script of the objects will not run – so it can cause an inconsistent result.
