The eGolf is similar to the Leaf in that regard, and unfortunately not in a good way: between debut and first delivery, VW decided to remove liquid cooling capability. The car was originally designed to have liquid cooled batteries. Cost is the most likely reason for that decision.
Hopefully the eGolf does not suffer from premature capacity degradation to the same level that the 2011-2012-early 2013 Leaf did. However unlike the Leaf, there are no tools that I am aware of for a non-dealer-tech to measure the capacity of your battery, and thus no way for us to track degradation besides keeping a consistent log of charging and battery drain behavior.
The link that you provided to is pretty good information for any BEV/PHEV owner. It's best to keep the battery level indicator somewhere near the middle, say between 40-60%. More frequent but shorter charge cycles are better than infrequent but long ones.
