Most non-aviation people I speak to do not know the aircraft type they are travelling in and care even less.
That is because more than half of flights are around 1h , an the vast majority of the rest is less than 4 , so makes no real difference if you are in a 737, 320 or even in a CRJ or E190..
If you are flying over 10h I can tell you that people do know and look at the aircraft they fly. So much so that on routes where types compete , like FRA-SIN for instance where the A330, B777, 747 and A380 were avail , the fares on the A380 were always higher and the first to get full .
The same was briefly visible on Delta, where the 767s were competing with the A350 on some routes, but that was all before Covid..
