As such, I'm thinking of switching back to a wired mouse. The stuttering is more frequent when the two receivers are close together and less frequent when they are further apart.

I tried changing the USB port, disabling Windows 10 game bar, enabling it again (with and without 'gaming mode'), turning off the mouse software, turning it back on, disabling Origin in-game feature and turning it back on. Under the Basic Settings tab, disable Accelerated Vertical Scrolling and Reverse Scroll Direction.

Go to Change Mouse Wheel Settings > Change Microsoft Mouse Settings to open the Microsoft Mouse and Keyboard Center. Click the Mouse link to open the Mouse settings window.
