I have used only HiDPI monitors with X11 on Linux for about a dozen years and it has always worked perfectly.

However I use XFCE, where you can set directly the DPI values of the monitors, so that everything will work fine. I have heard Gnome users complaining about problems with HiDPI, but those are not caused by X11, but by a bad Gnome UI for desktop settings.

So HiDPI is not something at which Wayland is better than X11 and there is no reason to avoid HiDPI. At a higher DPI, OTF/TTF typefaces are rendered much more beautifully and reading becomes more comfortable.

I do not know if Wayland has any advantage at mixed DPI, because I have rarely used such configurations.
