Is it really possible for a spaceship to stand still and turn off all engines and just be idle in one exact spot in space like it happens in particular famous tv series etc? Wouldn’t the ship just continue floating away/moving on its own until you turn the engines back on?

The question is, full stop relative to *what*?
There is no zero velocity point in the universe that you can say is not moving at all and the more you look for one the more you learn about how this doesn’t exist. So the “full stop” concept in scifi is closer to “fully matching speed with something else”. And in space it’s totally possible to get really close to zero relative velocity; this is basically what “rendezvous” means in a space context.
