Yeah the ones you want I guess would be 1920x1200 with the height reduced by common (say Windows 10/11) taskbar and tooobars. It's never going to be perfect but you'd at least want to minimize letterboxing for the most common fullscreen setups on the most common platform(s). But you could throw in 1920x1200 full screen as well for good measure. Perhaps it would be better to letterbox randomly with say 20px width and 20px height, so it's just 1 chance in 400 to even return to the same reported screen size? That way you'd be even harder to track than if you are the only person running exactly 1000x800.
