Hibernate and suspend are different. I configure my laptop to suspend for 3 hours before hibernating. That means I can close the lid for lunch or a commute and instantly resume, but if I leave my laptop in my bag over a long weekend, the battery isn’t drained. Does it save much battery? Dunno. A few % over a few days maybe.

Don’t use Ubuntu, but are you sure it removed it and didn’t do the same thing windows does (i. e. hybrid suspend)?
Yes, the default is that you can’t hibernate to disk, I think they changed it back in the 2020 release.
You can add the needed packages, swap, configure grub, etc. if you want to use hibernate, but it’s not part of the default installation.
