Use ":terminal" in Vim for a better integrated terminal

Vim has a fully integrated terminal that can be accessed via :ter (:terminal) (run :help :terminal to learn about it):

• It creates a split that operates like a normal Vim window (switch/move via Ctrl+w and hjkl/HJKL)
• You can move around or mousewheel scroll by entering "normal" mode with Ctrl+w, N (N.B. capital N)
• Hit i to go back to shell/"job" mode
• While in "normal" mode (usual Vim navigation mode), you can copy ("yank") with y as usual
• In shell ("job") mode, you cannot paste using p and instead need to use Ctrl+w, ", " to paste/"put" (yes, two quotation marks--this apparently is pasting from a Vim register named ")

Context

As a long time terminal user, I'm generally interacting with the terminal via GNU Screen, which allows me to quickly switch between virtual terminals, split the screen, copy-paste without the mouse, etc. These days, tmux appears more popular (likely for good reasons like persisting screen splits), but terminal multiplexers aren't the only game in town.

Namely, Emacs has an integrated shell that supports copy/paste, Emacs movement shortcuts, and probably a lot more I haven't discovered. Regardless, I still regularly use Vim due to its lighter footprint and my own muscle memory.

I was aware of :shell in vi/Vim, but it's clunky and doesn't integrate with Vim--it's more of a way to leave vi and then come back easily. Recently, I was pointed to :terminal and it is so much better than :shell, thanks to the features noted above.
