I actually really like this summary which goes through all the references in detail. It raises one great point in particular, even if you don't want to get into the linguistics of gender in Greek (which also disagree with you unfortunately). The only two named angels in the Bible are Michael and Gabriel, both of which are male. The rest of it is a fascinating look at angelology in the Bible though (which has been a big hobby of mine since converting to gnosticism. Its wild knowing more about the Bible now that the catholic church thinks I'm a witch). I actually found this while looking up the Matthew verse though which this breakdown implies doesn't mention gender but I would argue that it does. It says neither married nor given in marriage which is a distinctly gendered aspect in that cultural milieu. I do wonder if you're maybe thinking of similar figures from other religions such as the Nordic Valkyries or Islamic Houri.
