> EtreCheckPro: Top Processes Snapshot by CPU: photolibraryd and photoanalysisd
Those processes take their time to inspect the Photos library. Quite often it takes several weeks-months. I wish there was a setting to speed that up. But I guess sometimes some rogue image or movie might get stuck in that process so it goes into a loop.
I have tackled that slow update process by never letting the Mac sleep for a week or so after importing numerous files to Photos (just dim or sleep the display). BTW I suspect that Desktop & Dock > Hot Corners: Disable Screen Saver overrides that so I set "never sleep" via Lock Screen Options and take care NOT to use that Hot Corner then (clumsy but it seems to work...).
One option to test that might be this: Copy the Photos library to an external APFS or MacOS Extended disk, make sure you can access it by Option-launching Photos, and delete the original from the internal disk. Then unmount the external disk and Option-launch Photos and create a dummy empty Photos library on the internal disk and via Photos settings make it the System Photo library. Then after a while check if those processes are calmed down.
Not much in the EtreCheck report. But some sources say that Chrome background processes might have an issue with apps like Final Cut so I use Firefox as a 2nd browser with Safari.
