Skyrim Graphic Overhaul Mod
Ok so there's no all in one mod that does this but there are separate mods that offer most of this functionality.Requiem will give you an hard-core RPG experience, and de-level enemies. I believe it also overhauls perk trees.If it doesn't I recommend Ordinator for perk trees.For an up to date graphics combination there are dozens of guides out there. If you're new to this perhaps Skyrim Mod Combiner would be a good place to start.For combat/magic i believe Requiem may do this already but if not I personally use Wildcat and Vigor.The most comprehensive settlement mod for me is Expanded Towns & Cities. The mod page will tell you what's compatible if you want to add more stuff.For a character creation shake up there's Character Creation Overhaul or Imperious.For Dragon encounters you have two options I know of. Don't do the main quest and Dragons won't spawn or install Timing Is Everything.
Opening Scene Overhaul. This particular Skyrim Special Edition mod as you can understand from the name, changes the opening sequence of the game. It effectively restores the dialogue which the developers decided to cut. Grab this Skyrim Xbox One mod right here; Forget AI overhauls, enhanced weather, rich merchants, or perk tree changes. If there's one single, critical, must-install mod for Skyrim, it's this bad boy right here. I lost count of the number of times the guards in a town started attacking me because I defended myself against a sudden vampire attack.
Skyrim Graphical Overhaul Modding Guide
I believe the MCM menu allows you to disable random Dragon encountersFinally for quests there are a few mods that bring together many different quests like dungeon packs etc. I am currently running through a 'full loadout' of Legacy of the Dragonborn which has A LOT of quests either integrated or patched intoHope this helps.
