You can bind copy-and-paste as well as any other text wrangling functionality to whatever you want and there are ways to make it behave like other platforms without too much difficulty. But why hamstring Emacs' copy and paste by limiting it to the simplistic version we're used to when you can copy to multiple registers and have a searchable history of copied text?
Font rendering uses Harfbuzz in the latest version and is quite good in my opinion, there's even color emojis. Scrolling is certainly better than any terminal emulator I've used, although there's no smooth scrolling. I guess everything is off if you're comparing it to a browser, but modern browsers aren't exactly paragons of UX either. But if you're comparing prettiness options like these, yeah, Emacs loses to VS Code. All Microsoft had to do was build a text editor on top of a browser engine to get those features :). I'd say Emacs is more extensible, though. Lisp machines and all
