obviously use spoiler tags if you wanna go into details but I'd thought I'd go make a topic as a response to Narukovore's Worst Ending's thread

Here are my choices: Red Dead Redemption 1 and 2, Cowboy Bebop, Breaking Bad, Better Call Saul, The Wire (I said best not the most satisfying), Legend Of The Galactic Heroes, End Of Evangelion, Silent Hill 2 Leave ending, Cyberpunk Edgerunners, Cyberpunk 2077 Phantom Liberty The Killing Moon, Witcher 3 Blood and Wine Regis Ending (CDPR know how to make godlike DLC what can I say), Metal Gear Solid 3, Nier Automata Ending E, The Sopranos, Bojack Horseman

I'm not including movies just because it's much easier to write a good conclusion for something that's 3 hours tops

Sonic Adventure 2 True Ending

-God of War 3
-Batman: Arkham Knight(Ignoring certain game that came after that shouldn't exist)
-Tengen Toppa Gurren Lagann
-Steel Ball Run

Panam ending in cyberpunk 2077

Aside from examples already mentioned, I'll throw in
Return of the Jedi (there is no Disney trilogy) and The Clone Wars Siege of Mandalore arc
Full Metal Alchemist: Brotherhood (03's ending movie is good but weird, Brotherhood/Manga's ending is perfection)
Samurai Champloo
Gravity Falls
Bone (the comics)
Avatar the Last Airbender's four part finale (I personally enjoy the comic sequels and I thought that Korra was good but very flawed)
Justice League Unlimited (since it wraps up the DCAU as a whole)
Toy Story 3 (4 is a decent 6/10 overshadowed by a trilogy of 10/10's)
Fraggle Rock
Return of the King
Back to the Future 3

I like the positivity focus

original Pirates of the Caribbean movie (perfect example of an 'and so the adventure continues' ending)
FMA: Brotherhood is just perfect overall, and the ending was the same as when you finish a really good book and are genuinely sad at reaching the last pages
Helsing: Ultimate
Castlevania on Netflix, the Trevor/Sypha/Alucard series (I haven't watched Nocturne yet), that ending felt so earned to me and I loved the post-credits scene with Dracula and Lisa
Avatar: TLA
RDR2 especially as high honor
Ghost of Tsushima spare ending
Baldurs Gate 3
Final Fantasy XIV's story up to and including Endwalker "Remember us, remember that we once lived."

The Shining - The final part of The Shining is such an amazing payoff for all of the tension and bad vibes the film slowly builds up, ending in an explosion of violence, aggression, horror, and artsy batshit insanity. It spends 80% of the runtime putting you on edge, and then pushes you off as hard as it can.

Combined with the genuinely disturbing orchestra/choir soundtrack, it's damn near perfect.
Holy fuck I love that movie.

Eh, don't crucify me but I think Kubrick's The Shining is just...all right. I think maybe all the hype around it just ruined it for me, it did nothing for me and the other highest rated horror movie, Psycho, actually scared me and put me on edge. Really I think Scatman Crothers was the only thing about The Shining I genuinely enjoyed, him aside it's nothing to write home about. The Changeling came out the same year and it's easily so much better and way scarier.

Sorry for going off topic.

I like it when an ending takes time to wrap things up. Makes it more like a complete story, gives us time to take a farewell from the characters.

A controversial example is to show what I'm thinking about is the first Lord of the Rings movies. I'm generally critical about the changes they've made and the overall fan-finction level screenplay, but beside that I think letting the last movie run like another 30-60 minutes after Sauron's defeat was a good choice and very much in line with the spirit of the books.

In anime, Re:Creators is an example. If I remember correctly, It has like a full episode dedicated to closure after the final confrontation is done.

Here's my separate list for movies just cause there's so many to pick from:
Se7en
Godfather Part 2
Oldboy
Terminator 2
The Good The Bad & The Ugly
Harakiri
Scarface
Django Unchained
The Thing
Blade Runner 2049

Again it's easier to pick from movies cause it's much easier to wrap up a self contained story that only takes a couple hours to go through so I can't really judge them the same way I would a video game or tv show
