Polish works on any existing. Convert uses the current LIBRARY metadata.
So no need to run polish on a fresh conversion.

* Do I need the opf file if I embed the metadata? If not necessarily, how can I stop Calibre from creating it?
That is the backup (along with the cover image) of what shows in the GUI and is there to recover from corruption. It is a tint tiny file, whats the big worry. multi-TB HD's are cheap
Quote:
* Do I need to keep the "original_epub" file? Do I need to keep multiple formats per ebook? Can I set up Calibre to delete pdf or epub2 after converting?
NO as long as you don't ever want to go back. Preferences: Tweaks: # Save original file when converting/polishing from same format to same format
