IME, macOS (Monterey on M1 Pro) handles this better than Windows 10. Everything goes to the right places right away, whereas in Windows you'd have windows all over the place.
Windows 10 also, last time I checked, doesn't understand the concept of DPI properly. No idea if it's been fixed in 11.
That is, if you have for example a 27" 4K monitor next to a 27" 1080p monitor then the 1080p version is treated as though it's 25% of the size and the mouse gets "stuck" in the 4K monitor unless you're within the 50% of the screen that Windows thinks your 1080p monitor is adjacent to. This works sanely in macOS as it rightly treats each monitor as having the same size.
It's even more comical if you have a very high dpi laptop next to a 1080p or 1440p large desktop monitor.
That's odd; I never had any issues like these. Display ordering is always the same. I have two 27" 4K monitors: one connected directly to MBP's HDMI and the other through a USB-C hub (also HDMI). Connecting both always gives me the correct ordering, and it's instantaneous - it takes longer for the monitors to turn on than for macOS to distribute the windows, so when they're on, everything's in place.
