For the range I would need, and given only one lens I would go for the Canon 28-300L lens. It's an oldie but a goodie.

EF 24mm f/1.4L II USM is a favorite lens for astronomy, landscape, cloud, and sunrise/sunset photography.
My two favorite walk-around lenses:
EF 24-105mm f/4L IS USM
EF 70-200mm F/2.8L IS III USM

The 3 that get most used are 400mm f/5.6L, 70-200mm f/2.8L IS, 24-70mm f/2.8L USM,
but If I could ONLY own 3, then 70-200mm would be forfeit in favor of TS-E 90mm f/2.8;
Kenko teleconverters would get used even more often.
