High Isle is the latest chapter, so one of the High Isle editions should contain all previous chapters. It's the High Isle collection edition that includes all the other chapters as well. (Just checked.)
Not sure if this also includes all DLC's, but it does not mention that it does.

It does not include the DLC.
(edit: ESO+ unlocking "all the DLC" will get you everything but the current year's Chapter)
(Each year recently, they've been putting out a dungeon DLC, a Chapter, a dungeon DLC, and a zone/story DLC, all of them related to a year-long plotline. As someone who doesn't do dungeons, I've been fine with Chapter+DLC)
For the OP, I'd suggest getting the Collection (to add all the Chapters), then getting back to being familiar with the game. See if/how you like it, and which parts most interest you. Then you can decide to grab ESO+ for a month or two to do any DLC you want.
...you might also want to find a roadmap to the story progression, because with the "everything is scaled, you can go anywhere!" change they made in One Tamriel, you can end up jumping between stories, zones, and questlines very easily.
