Website width

I feel really conflicted and need advice before I start my next project. I was taught (at university, mind you!) that I should be building to 1920px on Adobe XD artboard and then developing online- currently, I do this on Webflow like everyone on here. I've recently been told by a designer that I'm doing it wrong and should be designed with a max container width of 1100px to better account for larger screens. I always check my designs on larger screens using google inspect and they look mostly okay as I used % as much as possible- except for the text size which doesn't always look the best when it gets up there in size. Is it best to stick with a max-width of 1100px? So I'm thinking I should design on a 1920 artboard on adobe with a 1110px guide? Or design on a 1280 artboard with 1100px guide? My clients usually sign off on design first in Adobe XD before I develop it so I want it to look good on the artboard too. Thanks so much for your help- sorry if this was a silly question.
