New follow-up : today,

$ xrandr
Screen 0: minimum 320 x 200, current 3520 x 1080, maximum 8192 x 8192
LVDS1 connected 1600x900+0+0 (normal left inverted right x axis y axis) 310mm x 174mm
   1600x900       60.0 +   40.0* 
[...]
HDMI3 connected 1920x1080+1600+0 (normal left inverted right x axis y axis) 531mm x 298mm
   1920x1080      59.9*+
[...]


The wrong refresh rate may explain the flickering on LVDS1 (but as I posted in #4, this is not always the case).

And when I boot without attached external monitor, 60.0 Hz is rightly
selected, and flicker is less visible (but not absent).

Dell support comes today, I'll see if changing the screen does any good
and report back.
