Two things in Temporary files are worth knowing about before you tick everything.
Delivery Optimization Files can be several GB, completely safe to remove. "Previous Windows installation(s)" is usually the biggest, but deleting it means you can't roll back the last big update. If the update has been fine for a week or two, delete it.

most of the 'clear your cache' advice does nothing for speed, it just frees space. the ones that actually matter:
Settings > System > Storage > Temporary files, the big one, especially the leftover update files. browser cache only if a site is misbehaving, otherwise it just makes everything load slower for a day. wsreset if the Microsoft Store is stuck. ipconfig /flushdns only for weird network problems.
skip the registry cleaners, they don't help.
