I'm posting this here for posterity.
I had to get my logic board replaced (yeah, spilled a little coffee! LOL). After this process was done; it shipped back with Big Sur, I restored my Time Machine (Monterey) and the heat and high CPU dangling issue has not presented itself since.
How, I've performed all the typical tasks before, resetting the NVRAM/PRAM, etc. etc. None of those tactics worked, this did. I don't understand what else may have changed here, but I wanted others to at least know this much.
