I once interned at a lab that used a piece of surely overpriced hardware that integrated with Simulink. You would make a Simulink model, and you’d click something and the computer would (IIRC) compile it to C and upload it to the hardware. On the bright side, you didn’t waste time bikeshedding about how to structure things. On the other hand, actually implementing any sort of nontrivial logic was incredibly unpleasant.

Maybe it’s different for those actually working in the profession and n=1 but in my (many) years of studying EE I never used these tools even once.

No not really, depending on the application Cpp or python has been the language of choice in the lab. Labview was used because it was seen as easy to make UIs for operators in production facilities, but even that was a regrettable decision. We ended up rewriting LV business logic in c# and importing it as a lib into a LV front end.
