I really have issues with the default behavior of deleting all dependent
packages like this without an obvious way to deal with it.

I suspect the official way is to is to use a set -o old-pkg:new-pkg:
pkg delete -f jpeg (-f prevents all dependent packages from being deleted)
pkg install graphics/mozjpeg
pkg set -o graphics/jpeg graphics/mozjpeg

Odly, I note that graphics/jpeg is a dependency of graphics/mozjpeg, so
color me a bit confused. I also don't understand why gcc and gcj are
dependencies. I guess mozjpeg requires the run-time libraries.

And why has Firefox decided to switch my language to UK English??? Weird
morning!
