I live in France. I’m a secondary school teacher. Never heard it used in the wild. Even by the teenagers. There’s a couple of them in each year group who have gone hard on LGBTQ+ stuff, but literally a couple. Most people would just scoff a bit about it.
Caveat - I live somewhere pretty rural, lots of them are the children of farmers/farm workers.
But I do know a couple of people desperate to demonstrate their woke cred who insist on saying «as a cis, hetero, white....» before giving their opinion. And being super right on about performatively explaining to their children that just because you’re born a girl doesn’t mean you have to grow up to be a woman etc. But they raise eyebrows. And they’re the kind of people who like to explain that they watch films in the original language without subtitles. I think they assume they’re well ahead of the curve by early adoption of an American value.
Interestingly I had a massive falling out with one couple like this this summer. I spent the weeks with them and realised he’s a giant narcissist and emotionally manipulates his wife. And announced this summer he’d had a revelation and he’s actually demisexual, to rapturous support from his wife... so they’re not selling it. (Also I started a thread because of them after they totally defended all prostitution, denied that nice men do it, and then the wife said she’d happily pay for sex
)
