I'd say that angels and demons are canonically agender in the book, but that it's more ambiguous in the TV show (Word of God notwithstanding).

Evidence pointing towards their being agender or some other variety of genderqueer: Crowley sometimes presents as male and sometimes as female. Michael and Uriel have male names according to Hebrew naming conventions while being played by female actors.

Evidence against: Aziraphale--the character we spend the most time with other than Crowley--presents consistently as male across a number of eras and locations. If God's gender (the literal God, not the creator of canon) can be assumed to have any relevance to the subject of angels' and demons' genders, then God in the TV series has a female actor and iirc is consistently referred to using She/Her pronouns by anyone who knows Her personally.

Evidence lacking: We don't get to know most of the angels and demons well enough to say anything really definitive about their genders.


But as for Crowley in particular, I considered him genderqueer on the basis of canon, even before seeing Gneil's comments on the subject. I sat up and noticed when Crowley was presenting as a woman in the crucifixion scene. Then during the Nanny Ashtoreth scenes, I was braced for a bunch of unpleasant humor regarding the situation that just...never materialized. At which point I concluded that canon wanted viewers to take female-presenting Crowley seriously and as an integral part of Crowley's characterization.
