Nah, the super long delays and animations are by design and make a lot of features like mission control & workspaces unusable. But, if you can tell me a way to switch between only the two most recent windows (note: I said "windows", not "applications") with a single keyboard shortcut and no animation delays, I'll love you forever.

I don't think that's possible but there is a by default unset shortcut to switch between windows of the same application. I set it to command tilde. And there are configs to make animations instant.

It's set to that by default.

Not on mine it wasn't, I assure you. I just set up a new Mac earlier this week.

Natively I don’t think so. macOS thinks in terms of apps, not windows. Personally I prefer that way but I understand how it can be annoying. There’s AltTab to fix that (freemium but open-source).
