As usual... if someone specifically requests words like that for themselves you do that. It's their choice.
But most disabled people prefer identity-first language like "disabled person". No euphemisms.
There are some who prefer person-first language like "person with a disabilty", although it's mostly parents who prefer that.
Just make sure you at least talk about disabled people how they want to be talked about.
Better: talk to us and let us do the talking about us.
Also, there are quite a few differences between (and even in) specific communities, because - wait for it - we are not all the same 👻
In Germany for example, people with what you would call "intellectual disabilities" mostly prefer the person first version "people with learning difficulties". In othter countries it's "person with an intellectual / cognitive disability".
You just learn it and respect it. It's that simple.

Thank you, I wasn't aware of the terms "person first" and "identity first" for these things!
I'm usually (in German) fairly specific in a "person with a xxx disability" whenever it's doable, since most of the time I talk about a specific set of disabilities at a time. I'm never quite sure I get it right, of course.
(Bonus: das hilft mir auch, weil "behindert" an meiner Grundschule *das* Schimpfwort war, und ich mich deshalb vor dem isolierten Wort scheue...)
Oh and please: if you feel the need to explain your views on disability from an abled perspective to me - just don't. I'm not interested.
