Quick answer

There is no stacking switch in One UI 9: notifications from the same app stack by themselves. Swipe down and tap the number on a stacked card to open the group; tap the arrow next to the group name to fold it again. Sort and filter notifications only changes the order.

If you do not see this option

Searched Settings for group or stack? On ours, group gave only Developer options and Bluetooth hits such as Allow group message, and stack gave nothing for notifications.
Want per-app categories? Notifications, Advanced settings has Manage notification categories for each app. It was off on ours; the page says it adds a categories menu to each app's notification settings.
Looking for the battery percentage too? One UI 9 has no Show battery percentage switch either: the number sits inside the battery icon, and Notifications, Status bar only has Show battery background.

If this does not work

Cleared a stack by mistake? Samsung says Notification history stores recent notifications even if they are dismissed or cleared. It is under Notifications, Advanced settings. Source: How to Enable Notification History
Pop-ups are bigger than the stack? Notification pop-up style sets Brief or Detailed pop-ups; Brief was picked on ours. Google notes that settings can vary by phone. Source: Control notifications on Android
