Which Thermistor to Choose

Hello fellow RatRiggers. 2+ years after receiving my V-Core 3.0, starting the build but being unable to continue it. Ordering and receiving the 3.1 upgrade, rebuilding the 400, again not being able to finish the build short after receiving it, I finally finalised it last weekend.
Lucky for me RatOS 2.1 just was released (temp release but I tried it anyway).
Feedback. The auto flash and semi auto flash do not work flawlessly. I had to shut down the power to have my Octopus Pro 446 rebooted properly. Also the timeout works fine so both Octopus as my toolboard needed repeatedly a retry but eventually everything worked perfect.
Question: I ordered the 3.0 with a mosquito magnum hotend and a NTC 100K B3950 thermistor at RATRIG. In the 2.1 pulldown it shows a 100K with a different type or generic B3950 thermistor. Which is the one to choose? I chose the generic B3950 for now. Is this the right one or should I choose the 100K? If so how and where to change it.
Question 2: If I change nozzle to CHT what do I have to change (I now chose the regular nozzle)
Apologies for the (maybe too) long story but I hope someone will be able to answer the questions.
