"If you tell Ukraine to just surrender the parts Russia want, please point to the parts of your country you would surrender if one of your neighboring states attacked your country."

Sounds like a win-win to me!
The safest way forward is for Russia to be comprehensively defeated in Ukraine.
You cannot appease a fascist state.
