I have a heating blanket for Saison.
I use one of these seedling heat mats as my heat source inside a freezer. They're built to have stuff sitting on top of them, they're water resistant, and they heat gently. Seems pretty safe to me. That said, you can make any of these options much safer by plugging your temperature controller into a GFCI outlet.
I use a reptile heater bulb that uses infrared radiation for heat. Works great, no light to skunk beer, very safe.
The aquarium heater is probably the safest. The ones I've used before have their own controller, they're probably fairly reliable (nobody wants poached fish in the aquarium). Along with the water bath, you'll get good heat transmission without much hysteresis. Assuming you have reasonable insulation, and you're not brewing in the artic, <100W should be ...
Depending on the type of temperature probe, you could use 2 of them in parallel, one in the middle of the wort and one taped to the side of the vessel to get a rough "average" of the reading of the two probes. Use the same probe type, wire, and wire length to help eliminate any difference in resistance that would affect the reading. Mathematically it won't ...
The temperature will vary, but as fermentation proceeds we will be generating CO2 which aids convection within the fermenter. As such you should not see a large difference, but if you see any then measure 1/2 way.
