A quick update to my post from yesterday – Adobe also released Lightroom Classic CC 8.1 with support for the Nikon Z6. See also the full list of newly supported cameras and lenses.
The latest Adobe CC plan rates can be found here (see also this page). You can get a free Lightroom CC trial on this page (no credit card required). More information on the different Lightroom versions is available here and here. The different Adobe Creative Cloud options are described here.
