In what ways was Georg von Trapp (of The Sound of Music fame) opposed to Nazi ideology as is stated on his Wikipedia page and the National Archives page it references.

Do we have sources about his political beliefs outside the personal record provided by his wife? It seems suspicious that a wealthy rural Christian patriarch in that time and place would be opposed to the Nazis or fascism more generally.

You're quite right to be suspicious. He was a fascist (specifically an Austrofascist) who opposed the Nazis over the issue of Austrian sovereignty. Please see this excellent post by /u/CommieSpaceInvader for all the details.
