I'd recommend BetterTouchTool and things like finger swipes for volume up/down and brightness up/down and showing things like Spotify. Originally started with Vas3k preset but eventually replaced things with the built in widgets and gestures
Another small but nice utility is Haptic Touch Bar. It uses the click feedback mechanism in your trackpad to make the computer tap slightly when you hit the Touch Bar.
Makes it feel a bit more tactile and I'm surprised Apple didn't build some sort of feedback like that in by default.
Using the trackpad mechanism is a little cheesy, but it could have its own haptic hardware.
My favorite BTT mapping: 3 finger click (touchpad and/or magic mouse) generates a middle click event.
I have no idea how people open and close browser tabs without this, since browsers have great middle click response but Apple pointing devices don't natively generate such clicks.
I just realised I've been using this with BTT for months now, it's so natural to me that I just assumed that it was built in. Just checked and saw that it's the only touchpad addition I have in BTT.
One giant button in the left corner that says "escape escape escape escape escape" (what it does should be obvious), and one tiny button in the right corner that brings back the normal touch bar. (And nothing else.)
Also, make those buttons white text on black. At least it's an OLED display, so parts of it you want "off" are actually dark.
Even just the lack of a bunch of distracting flashes as it changes when you switch apps is a relief.
