Connecting a Display Port 1.4 graphics card to the Dell thunderbolt dock WD22TB4
Most monitors have a Virtual Control Panel (VCP), which implements features defined in the Monitor Control Command Set (MCCS). This is a VESA standard. You can find the Input selection command in table 8-10. You send these commands over an I2C bus called Display Data Channel/Command Interface which is yet another VESA standard. If you are running Windows https://www.nirsoft.net/utils/control_my_monitor.html will let you use every VCP feature your monitor has. For Linux, https://www.ddcutil.com/ does this. For Mac, https://github.com/alin23/Lunar

Opinions on functional & performance requirements for a desktop TB/USB4 AIC
The protocol is called DDC , it's a VESA standard. In there, it's called VCP features. If you are running Windows https://www.nirsoft.net/utils/control_my_monitor.html will let you use every VCP feature your monitor has. For Linux, https://www.ddcutil.com/ does this. For Mac, https://github.com/alin23/Lunar note how all three mention input selection.

A related non rust tool (that also has an optional GUI) is ddcutil. How does this compare to that?

Brightness issue
I've also used ddcui: https://www.ddcutil.com/#introduction, available as an AUR package: https://github.com/rockowitz/ddcutil. This has a nice GUI: https://www.ddcutil.com/screenshots/ddcui_features.png and works on everything I've tried it on out of the box.

Is there a good software to change monitor settings and create profiles?
You may have to, however, figure out the control scheme yourself, with something like winddcutil and then use it inside of a batch script or some simple app. I was able to figure out most of the settings iirc on my MateView monitor, from brightness to gaming profiles.

Question about OSD Sidekick with Dual Monitors
It may be possible to control multiple monitors if you're decent with Python https://github.com/P403n1x87/m27q/pull/1. It might also be possible with DDCUTIL (for Windows - https://github.com/scottaxcell/winddcutil) if you're willing to go that route.
