I cook most fish (including prawns) to 45C / 113F. That is below the sterilization limit. That is perfectly OK within food safety guidelines so long as the cooking time is not too excessive (i.e. so long as it is less that a couple hours). I would NOT cook thick pieces of fish this way because the cooking time would be so long that some spoilage could result.
Beef and other red meat I cook to 130F / 54.4C. This is what I would term ������������������������������������medium rare������������������������������������ but there is a lot of disagreement on mapping subjective terms like that to temperatures. Depending on the situation I might cook it to sterilization, or I might not.
Tough red meat ������������������������������������ such as flat iron steak, short ribs etc I will cook at either 130F/54.4C or 136F/58.8C, from 24 to 72 hours depending on the cut and how tough it is. This gives time for the collagen to break down and make a tender result.
Tender cuts of pork, such as tenderloin I generally cook to 140F/60C. Trichinosis is killed at 137F, and anyway has been eliminated from the food supply in the US and many other places. I would cook wild meat a bit more, and/or pre-freeze it.
Chicken and turkey also gets cooked to 140F/58C, and I make sure that I follow the sterilization times.
Duck breast goes to 130F/54.4C. Duck confit is 180F/82.2C for 8-12 hours ������������������������������������ pork or lamb confit is the same.
The thighs are cooked very similar to the manner in which you'd cook a duck confit. You might want to try making it even closer to duck confit - see the duck confit thread. Basically, you salt the thighs/legs and let them sit (brining also works). Then cook with several tablespoons of buttor or oil in the bag. I'd try 170F to 180F for 8 to 10 hours.
