ro has no remaining effect long before starting Xorg or sddm are attempted. From 
the man page:

	ro		[KNL] Mount root device read-only on boot

Is Plymouth both required and installed on your systems? If installed and not 
required for your configuration, try disabling it, or removing it entirely.

It seems as though you are equating the FOSS Xorg driver named modesetting with 
kernel modesetting (KMS). They are not the same thing.

The proprietary NVidia Xorg driver, unless something has changed lately that I'm 
unaware of, requires that KMS be disabled (exclusively via kernel cmdline???, 
such as nomodeset or *.modeset=0) in order for it to function. AFIAK, as I've 
never tried using it, AMD's proprietary drivers require the same.

Disabling KMS via kernel cmdline disables these FOSS Xorg drivers:

	Intel
	AMD/ATI/Radeon
	Nouveau

If you have a new enough (but not bleeding edge) "big 3" gfxchip, and have 
neither the NVidia nor AMD proprietary drivers or any of their remnants 
installed, nor any of the "big 3" FOSS Xorg video drivers installed, then the 
modesetting Xorg driver should be employed automatically, and probably 
sucessfully, at least for some definition of successful that does not include 
high performance gaming.
