> Can you at least get from Control Center to the corresponding Settings page easily now (long press, hard press, etc)

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.

Can only check on iphone, but long press on wifi, then again on wifi on the subsequent menu (where you can select which network to connect to) has “wifi settings” at the bottom.
