As someone with a number of friends, family and colleagues on the spectrum, and a wife who works in SEN, I would say the best source of knowledge would be to seek out people with first hand experience to talk to.
There are books with people’s lived experiences that might be helpful too - I’m actually currently reading “Secrets of the Autistic Millionaire” by David Plumber.
Finally, sounds silly, but there are some fairly meme-y groups on here that can still offer insight, e.g. autisticandadhd@lemmy.world
For me in the UK:
BBC News is okay, but it can sometimes tie itself in knots trying to be it’s definition of “unbiased” and gets slated by both the left and right for it. There was a specific controversy recently where they were accused of bowing to the government.
I like The Guardian. It’s left-leaning in it’s opinions, but not to the extent of overly spinning the truth.
In the last few days I’ve actually been trying out Al Jazeera. Early days, but I’ve been very impressed by how ‘dry’ their articles are - very matter-of-fact without spin, unlike the usual Western style.
