I am using CATALINA with Magic Mouse 2 (Bluetooth).

Just a thought: Since any mouse clicking is a manual exercise, it does make sense to me that there would NOT be any provision to adjust this speed in Preferences.

Similarly, there is no option to modify the click speed of Magic Mouse in BTT, either. Presumably, one's own hand controls the space between clicks.

P.S. On the other hand, the non-clicking motion for mouse 'tracking' makes sense and is an option in Preferences.
