Laptop screen for outdoor use on sunny days

I use my personal laptop predominantly outdoors in the sun. My experience with previous laptop screens have been from "can't see anything" to almost acceptable(400 nits matt screen on HP elite x360). And therefore, the laptop screen has been often the limiting factor for productivity, not processor or RAM. (I am an average user, who needs browser, excel and word most of the time) Since I need to buy a new laptop, I am trying to figure out what kind of screen is best for this kind of use. Below are the criteria I found so far, I would appreciate any inputs based on your experience.

1. Matt or non-reflective screen. This, in my experience, makes a huge difference.

2. brightness, approximately above 500-600 nits.

3. not having screen privacy features like HP Sureview, since they reduce the screen brightness and not necessary for simple private use. I've got nothing to hide :D

What do you think of the list above?

I currently have a work laptop (HP Elite X360 1030 G8) with matt screen with 400 nits, which is barely visible in the sun. But there are no reflections on the screen and it is the best screen I have used so far.

Fewer laptops in the market have matt finish screens, mostly ultra-thin laptops from HP, lenovo, Dell etc. And very few of them have above 400 nits brightness. So, I am mostly finding either high-nits glossy screens, or matt screens with upto 400 - 500 nits, or 1000 nits screen with matt finish and privacy features reducing their effective brightness back to 400. (example of last case: HP elite x360 830 G8) Which one would be a better solution, in my user case? Does anyone have experience in this, and have any recommendation for laptop models or series etc.?

I searched reddit, but couldn't find any relevant information. I would appreciate any help!
