an aircraft, there's just thin air outside, so I'd presume it'll mildly
keep sliding sidewards too (in the opposite direction) while turning
about its axis. It might just feel like in a briskish whirligig.

I've never been in a briskish whirligig, so I don't know, but, when you make a
rudder turn, momentum attempts to have the contents continue in a straight line.
In some areas of a large aircraft, unsecured cargo would slide sideways in such
a turn. In a coordinated turn, the forces of momentum and gravity balance out.

As far as passengers are concerned, uncoordinated maneuvers tend to make them
nauseous. This effect is stronger the further away from the center of the wing
they sit.
