WU automatically install new components of new updates, not the complete package so if you already have 4343887 installed, WU calculate and check components in 4343884 and download new ones in delta-generated binaries
1607 is a feature update, regardless the build lab according to pkeyconfig.xrm-ms, all new keys for Server 2019/Win10 are in [RS5] range
Quick question. Did some of you had your update history cleared when you installed the latest cumulative update for build 1803? Mine did after a fresh install of Windows 10 (cause i messed something up lol), so I'm just asking if that's a normal occurrence when a cumulative update is installed. Overall, I have 95 updates installed for MS Office 2016 and 4 Windows update.

That is the update which sets the old build to receive the new coming upgrade (it is (re-)released every time a new upgrade will arrive soon).
