News Web Part Filter Not Available
I think the ability to filter on news across site collections is supposed to be coming at some point. What you can do now is use the Highlighted Content web part to pull in news articles from multiple site collections and then filter on a managed property. When I need to do this, I create a managed metadata property that I use on all of the sites I want to roll up and then map each property to an available managed property in the search schema (e.g. RefinableString05). Then I can filter the news based on that shared property - but for now, only in the Highlighted Content Web Part.
I don't think so,. Find more information here: https://docs.microsoft.com/en-us/sharepoint/manage-search-schema.
For clarification to Susan's response, from the link...
"You can create new, custom managed properties, but these can only contain text or Yes/No. If you need other content types in your custom managed property, then use one of the unused, built-in managed properties that search comes with. These managed properties can contain information in integer, decimal, date and time, double precision float, or binary format. You can "rename" these unused managed properties by using the alias setting."
