Do they turn straight for the target or do they somehow can calculate (or get data from ship if wireguided) it's speed/course and go towards the "meeting point"?

They head straight to the target. There is no course-prediction capability, nor would you want one. Dead reckoning of the fish is used to determine for the fire control team where it is when it acquires. The torpedo starts "Range-gating" where it immediately pings when it gets a return. The time of pings corresponds to a distance from the torpedo using speed of sound in water. Add the 2 together to get true range to the target.
This is also a way to get the range of a torpedo that has acquired you.
It is quite un-nerving to be in a boat when a torpedo is range-gating on you. I experienced this is the sonar shack when we steered a practice fish 180 on the test range to prevent it from running into a wall. You maintained depth separation, but it was pretty eerie. The active-intercept receiver makes a high-low tone that gets progressively closer together.
