I have a 2020 Intel iMac and currently running macOS Monterey 12.6. Will upgrade to macOS Ventura 13.0 tomorrow or within this week. Working with a lot of different Mac at work, macOS Big Sur was never been smooth.

macOS will fully support Intel CPUs until one day it doesn't and you can't even upgrade to the new OS version anymore. So it's not your decision to make, Apple will decide when your computer is too old. Usually software and hardware support lasts up to seven years after Apple last sold the device as new.
As it's always the case, you might miss out on some new introduced software features, which specifically require a hardware element your Intel Mac doesn't have, like a Neural Engine. Those features are just missing while the rest of the OS works as advertised. Generally speaking upgrading macOS has often been a joy bringing genuine performance improvements and bug fixes. Occasionally a new user interface design turns out to be not as great as Apple thought. You get the good with the bad.
That used to be the norm. Apple has recently stated that they will only commit to security updates for the latest major version of macOS; prior versions may get some security updates, but they are expressly not guaranteed to get all of them. (Reference)
