Trash on the sensor shows up when the lens is stopped down. Both of these
shots are f/8. Exif doesn't say what mode. I'm going to guess as you go to
full zoom the max aperture is reduced, hence why these only show at zoom.
Set the camera to aperture priority and set the most stopped down you can
f/8 or more and take a wide angle shot of the sky to see it it's still
there. Sure looks like something on the sensor to me.

Yes

Looks like sensor dust to me.

Actually, many P&S cameras have an integrated sensor/lens assembly so
they'll have to replace the entire optical assembly (probably cheaper
to replace the camera).
