From what I understand, there are two main methods for CPU stress testing. One involves intense tests such as Prime95 or IntelBurnTest, which run for many hours, while the other uses lighter workloads like x264 Stability Test overnight. For my work involving CPU rendering, I need a stress test that can handle prolonged use, similar to Corona Benchmark or Cinebench.
A stress test that pushes all the CPU threads to 100% is the best bet as it shows that the CPU can cope in a worst-case scenario. The Prime95 Small FFTs test does this.
The problem with emulating a typical workload is that there's no such thing as typical. A CPU overclock may work just fine in Cinebench but may crash during another application that's more CPU intensive.

I will continue using the intense stress tests to verify the system's stability, since I'm satisfied with the performance improvements from the overclock at the present voltage.
Thanks. I plan to continue with the extreme stress tests to confirm the system's reliability, especially since I'm already satisfied with the performance improvements from the overclock at the current voltage. Just in case, I would run the test overnight to ensure stability, as a single hour or two isn't enough. I actually performed an Intel Burn Test after confirming stability, and then used Prime95 for 8 hours.
An FFT size between 8k and 16k with a maximum of 8k is suitable for stability testing under full load. Prime95 version 26.6 can also be employed to assess stable performance without AVX, achieving higher stable clock rates: http://overclocking.guide/stability-test...-prime-95/
Thanks! This makes it clearer why temperatures are so high in Prime95 compared to other tests I've run.
