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
