Damsel just came out this year. Haven't seen it yet, but the trailers looked good.

The d&d movie, honor amongst thieves has a damn fun dragon scene in it, and it's more than a simple one-off imo. It's borderline though, might not be what you're looking for exactly, but worth watching. There was also an older d&d movie that was built around dragons. As a movie it was kinda meh, but the dragon parts were decent. That's the one that wasn't on the syfy channel. The TV one was meh across the board.

There was eragon, but I've never seen it. A lot of people that were fans of the books hated it, but maybe someone coming to it fresh wouldn't.

Dragonslayer is much older, it came out when I was a kid. So, don't expect great effects by modern standards, but it's an awesome movie.

There's the Hobbit movies. The Dragon, Smaug is central to the story, though not present until the end.

Reign of Fire was pretty damn good at the time, though I don't know how well it holds up. But I still like it enough to watch it now and then.

Oh! And dragonheart! A brilliant movie that absolutely holds up.

Those are the ones I can think of.

Now, I didn't mention any animated ones. That's because I don't really think most of those do Dragons justice, not the ones that meet the featured criteria anyway. Like, Pete's Dragon is awesome, a great movie. It just isn't what I think of as a dragon movie. Same with Spirited Away, which has a dragon as very integral part of the story, but it isn't a dragon movie in the same sense as The Hobbit is.

But, if you want animated options, those two are a great place to start.

Obviously, there's also the game of thrones stuff, but that's series, not movies. Great dragon scenes for sure, and they're integral to both series.
