You can't really simplify the information displayed by HWiNFO, CPUID, GPU-Z, etc, the Wall Of Numbers is just part of their power.
You can get more simplified summaries directly from UEFI/BIOS screens.
My mistrust of CAM is largely based on the annoyance of user logins/tracking.
I don't like stuff which keeps on calling the mothership - partly because I'm running software which isn't fully under "my" control, part of it runs on somebody else's computer, it could be changed or "broken" at any time - and partly because I observe a general philosophy that "the more they sell it, the less you need it". CAM's user/data analytics are basically benign but still more pervasive than I feel really necessary so I'll continue to use less intrusive alternatives. But that's just me and what I value. If CAM provides features (like simplified interface) that are valuable to you then CAM is a good option for you, nothing wrong with that.
CAM is a "widget" sort of background process. Always running in background. Same as things like ASUS AI Suite or DIP5 or Fan Xpert softwares.
By their very nature, running softwares always occupy some CPU time and some memory space, not a lot (hopefully) still something which needs to be considered when viewing the numbers they report. Always-running things like CAM have to be bigger and bloated more than run-and-terminate things (especially in a Windows OS, lol).
I like to minimize running processes, remove those which aren't required to free up resources, keep the system lightweight for maximum stability and performance and responsiveness. Hardware monitoring isn't the sort of thing I need to have constantly running, so I prefer software which can provide the needed information on demand. Use it when needed, put it away when no longer needed. System configuration through firmware (user BIOS) or hardware (like a fan controller) imposes no additional runtime load, offers the Wall Of Numbers type of fine control I (but not you) happen to prefer, and (very importantly) cannot get changed or "broken" anytime a piece of software (or one of its subcomponents, likely coded by a different company/dev) gets updated or when it fails to login to somebody else's remote server.
CAM seems a good choice for your needs. I think any "abnormal parameters" it reports should be always confirmed by consulting a Wall Of Numbers, though it's not strictly necessary.
