Now do the same comparison with Z 50mm f/1.8 and Z 24-70mm f/2.8 ;-)

Okay.

Sony/Zeiss Sonnar T 55mm f1.8 official Sony price: €1100,-
Nikkor Z 50mm f1.8 S official Nikon price: €679,-

Sony FE 24-70mm f2.8 GM : €2500,-
Nikkor Z 24-70mm f2.8 S : €2499,-

You forgot to mention the Sony FE 50mm f/1.8 ;-)

And in terms of street price, we are talking about 2050EUR for the Sony 24-70/2.8 and 2350EUR for the Nikkor.

The Z 35mm f/1.8 (800EUR) has no direct counterpart but the FE 28mm f/2 (400EUR) should have a comparable price tag - but obviously ...

The RF 85mm f/1.2 will cost 3000EUR - the Sony FE 85mm f/1.4 goes for 1700EUR at the moment. Sure, not comparable but that difference is not just a little there.
