That's a great list!! I hadn't heard of half these tweaks, nor did I realize there were so many that work on iOS 13. Maybe it's time to jailbreak again!
Give it a shot! A complete restore ("Set up as new iPhone") will remove 100% of any trace of any jailbreak should you decide to go back to stock. Unfortunately restoring an iTunes/iCloud backup can restore files to a non-jailbroken phone that can trigger certain apps' jailbreak detection. I've never had a problem with that, but so I've read.
