Those are covered too in their build specific threads.. Enterprise (N) 2015 LTSB (10240.16385 TH1) covers all important Enterprise 2015 LTSB info.
Yea, end is very soon. I only have it for completetation and customize reasons. Like I work a lot with NTLite and make some compares and test so figure what came new and can be removed safely. One thing where this is useful : Compare 23H2 with 24H2, as my micro suddenly got not detected anymore with the newer build. If you need a Windows 10 like for productive use, I would go for 21H2 Enterprise LTSC (IoT afaik)
