There's a bunch of screenplays in there to read if you want to learn how screenplays are written in case you're trying to write a short story or something. The only caveat I found is most of what's in there is unused drafts that don't really match up with their movie counterparts, but the writing is good enough to learn from. Just don't try to match up the movie with its script from that database in your head or you might get tilted.

This comes with a more limited collection of screenplays, but what's cool about it is some screenplays come bundled with outlines and synopsis which is ground 0 for writing stories. Good to see how people tackle that stage of the process.

This comes from a community of screenwriters, many of which are Hollywood professionals, so it's not a surprise that they gatekeep it. All you have to do is fill in a form that they have in their Discordand hope they accept you. I wouldn't say the number of screenplays is any bigger than scriptslug, but it's still workth checking out.
The one thing I still struggle to find myself is animation-oriented stuff. I get that animation and live action are basically written the same way, but it there's certain stuff in animation that unless you have the diction for, it's kinda tricky to describe in as few words as possible.
