They do work, provided the boss doesn't rotate. This is more of an issue in higher level duties, especially in Endwalker, because of how the bosses re-center themselves all the time. It's annoying but since it's scripted you can anticipate them as well.
often I got hit by ground effects while clearly not standing within the area
That's mainly because the snapshot happens when the cast completes / the red telegraph disappears. If you were in it at this moment, you get hit, even if you subsequently run out. It takes a few seconds for the hit to be enacted, allowing you to run out of it still. Ping, SE waiting for animations to occur and server processing and all that.

I was watching Yoshi-P play the other day on BLM. I noticed something interesting, which was that an attack hit him immediately after the snapshot. It makes you wonder if SE has any idea that it's an issue because they have 0 ping.
