I do not believe any Summerset editions come with DLCs other than Summerset and Morrowind.
I thought there was one edition that did come with some zone DLCs but could not find it. There’s something called the “guilds and glory dlc megapack” which contains four DLCs - wrothgar, thieves guild, dark brotherhood and imperial city. That’s what to look for on the bonus list of the edition you’re buying.
The DLC zones can be obtained by buying a monthly sub through ESO plus, which opens all zones while the sub is active and gives you 1500 crowns per month that you can use to permanently buy dlc zones. Or you can pay cash for crowns and buy the DLCs that way.
