4K display will have less screen door effect. If you are worried about scaling, 4K screen can show FHD content 'natively' just by quadrupling the pixels.
1080p content will, all other things being equal, look better on a 1080p display than a 4k one. What collusion mentioned would be called integer scaling and almost no software does it, they will nearly all use bilinear or some sort of spline filtering to get to 4k
The screen door effect may still be noticeable on a laptop but honestly, at least IME, it's something you can learn to live with. 1080p displays are often higher refresh rate for equivalent price and that matters more to me, and you'll not be needing as powerful hardware to make the most of it. 4K is better-suited to larger (32in and above) desktop monitors.
