Not really, but they are alternatives to each other. Bottles can also be configured to run “normal” applications alongside possible games and stuff, while Lutris has more a “gaming” UI vibes (but you can run everything you want on both of them really) and additionally provides some integrations for other emulators. I think it comes down to personal tastes at the end of the day, both of them under the hood use wine/proton and apply settings to it before running the application

It could be interesting to create a distro-package (I think it would be very easy to make one for deb/rpm/arch packages) with all these aliases to make them easily available to other people too.

They already suggested yt-dlp, but also have a look at JDownloader. You can paste a webpage url and it will fetch all the elements it can download, video included. You can also create download collections in order to download the same files again (or in another computer with JDownloader installed).
