The problem here is that most points are about how to formulate your ask. I think the biggest thing is that you're much more likely to get help if you show you're doing the best to solve it yourself.

There's a big difference between:

"Hey, I saw this job at [company you work at], could you refer me please? I'm [lists skills and experience]"

and

"Hey I'm thinking of applying to [company you work at] for the product designer position and I want to make an impression, so I'm putting together a demo Figma with a couple of things I'd fix and how. I spotted those when I did the onboarding for your free trial. I'm curious if you could tell me whether [design flaw] is intentional to deter abuse or if that's something I could fix? Totally get if that's confidential"

The part where you're solving the problem instead of hoping someone else will solve it for you, that's much more important then how you word it.
