Where do you see meaningful progress coming from? To read into your response a bit via "I would be surprised if they’re substantially wrong", are you saying that sex is binary and immutable in humans? That's a falsifiable claim, and progress could be made by either proving or disproving it.

they’re too busy policing women’s bodies

I think the standard answer is "Men should just respect women's spaces". What do you tell someone that agrees with "The biggest threat to women’s safety is men" and also believes sex is real, i.e. a TERF? It doesn't seem like a lot of progress will be made with "The biggest threat to your safety is just a distraction"
