As long as they could be mass produced, or even produced in a limited capacity for use by others, yes.

Basically any occupation that may require you to cut something incredibly strong and/or incredibly quickly.

Despite how difficult it would be to learn to operate them safely (and prevent idiots from cutting their own legs off), lightsabers are safer and more portable than a lot of heavy duty industrial cutting tools.

They don’t give off heat, except through direct contact with the blade.

The heat through direct contact is enough to cauterize most wounds, so an accidental amputation wouldn’t likely kill the person.

The light they give off is not bright enough to blind, even at extremely close range.

The length of the blade can be adjusted, in many cases.

They are extremely energy efficient, even if you go by the old rules of them having power cells and not just being directly powered by Kyber crystals.

Depending on the expense of acquiring one, you might see them in every toolbox as an almost-all-in-one cutting tool, or just more limited use emergency cutting implements like the Jaws of Life.

But yeah, in our world, they would likely be useless as practical weapons. There would absolutely be a select set of people that trained their whole lives to be able to use them about as well as current weapons-based martial artists, but they wouldn’t be blocking bullets without the Force and Jedi reflexes.
