After updating to previous new OS I have lost various photos and videos plus the loss of iDVD, iPhoto, iMovie library, Time Machine and Dashboard. The update information never mentions that these features will be missing on the new OS.
What features can I expect to NOT get if I update from Big Sur to Monterey.

You do not state what macOS that you are currently running...? So it is hard to speculate.
If it is Big Sur to Monterey I would expect no issues.
It never pays to get too far behind in the software or hardware—this only makes in more difficult facing an accumulation of outdated /deprecated apps etc.
Your example iPhoto was deprecated in 2015 and replaced by Photos.
I can say macOS Mojave 10.14 is the last OS to support 32-bit applications
32-bit app compatibility with macOS... - Apple Support
