The block or head for the coolant temp sensor. The block fro the pressure sensor.
If I understand your question, I always placed my oil pressure sensor in the block and preferably as far from the pressure pump as I could. For water, I had it at the water outlet from the engine, usually in the cylinder head. I did this so I could see any issues with either pressure or temperature as soon as possible in the system. I wanted to know what the maximum temperature and minimum pressure in the engine. This setup saved me on a couple occasions and avoided any serious engine damage.
You are right about not getting a water temp reading if there is no water at the probe. But if that is the case, the engine might be damaged. Prior to that reading, I would expect that the temp gauge would have been high. Taking a reading after the radiator does show how ell the radiator is working but not much about the engine.
If the water temp is at 220 and suddenly drops to 212, you're reading steam and don't have much time left to shut down the motor.
Ask me how I know this...

Water pressure is a rare sensor yo have but it is a good idea. My miata has one. It's just a dummy light, pressure drops it goes on. It flickers on warm up but always off on track. Certainly would be a good idea if you are worried about the rad dropping water.

This.
Longacre sells a pressure switch/idiot light kit, $30, just requires a bung to screw it in to... have this on my P2, easy insurance. Though I just got the pressure switch from them ($20), and wired it to a high-intensity lightweight LED marker light. Hard to miss at any speed!

Though it has been determined that not unlike the gauge sender, you want to install it low so as to not have false triggers at temp. Which may be an indicator of other issues... used to flicker a lot on my car until I moved it down low. At least it'll get you looking closer at the gauges if needed.
Then my rad cap expired, but that's another story...
