I find it rather tiring when there is no mouse speed setting. The only solution that worked for me is https://askubuntu.com/a/569345/196639

xinput list #get device ID
xinput list-props <device-id> #get Coordinate Transformation Matrix (<prop-id>)
xinput set-prop <device-id> <prop-id> <3x3 matrix>

#e.g. (for 0.2x speed)
xinput set-prop 10 154 \
                0.2 0.0 0.0 \
                0.0 0.2 0.0 \
                0.0 0.0 1.0

This is rather cumbersome. Is there some program I can install that gives me a mouse sensitivity slider that persists across reboots?

(I'm using KDE, but answers for all environments/WMs are welcome)

For reference, this is the usual interface, with no speed/sensitivity option: enter image description here

To make it permanent across reboots you can create file /etc/X11/xorg.conf.d/20-mouse.conf with the following content

Section "InputClass"
            Identifier "Mouse sensitivity setting"
            MatchProduct "<mouse_name>"
            MatchDriver "libinput"
            Option "TransformationMatrix" "0.2 0 0 0 0.2 0 0 0 1"
EndSection

where <mouse_name> is your mouse name from xinput list output, and 0.2 is the desired sensitivity, 1 is max. Make sure you are using Xorg, not Wayland.

And GUI for this feature probably will be added in KDE 6.
