Here's the diagnostic results for my 2017 iMac 27" that experienced kernel panics and it says had high cpu usage few times. I cannot figure out what's causing the problem. I suspect overheating but the Macs Fan Control shows about 99-102 degrees F at normal usage.

suggests a possible interference from one or more of your Safari extensions. Turn all off and test. If usage is normal, turn them back on one at a time. If the issue returns, the last one enabled is the problem extension.
The report shows your Fusion Drive is healthy and running at expected speed.
I do not have Cindori Sensi installed. The only app removal app is called "AppCleaner" I found that plist for Cindori Sensei and removed it. I hope that helps, we'll see. I kinda wish macOS removes other files that doesn't need anymore rather than digging for dead files. This is why I use "AppCleaner" for that purpose.
I’d remove the cleaner app installed here: Cindori Sensei
That’s a class of apps that can potentially cause surprises.
It crashed while I was using Firefox browser forcing a restart with a kernel panic panel at boot up.
