If you turn off wifi from settings instead of the control center (top right corner pull), it will stay turned off. If you turn it off from the control center, it will indeed say "Turning off WiFi until tomorrow".
You can, just long press the wifi icon in control center, it will expand to show all wifi points nearby. Then click on "settings" button, and it will take you to the actual wifi settings page in the settings app.
This isn't a recent change btw. Idk when they added it, but I remember using it since at least iOS 13 or 14, which was 2-3 years ago.
If you want, you can also just add that shortcut to lockscreen as well and do it via a single tap from there (which is also less clicks than even control center).
