Uncheck the 2 (Internet Explorer and Internet Explorer - 32 bit) to remove IE entirely. This problem of opening each folder in a new window has apparently been resolved in the latest versions of NTLite. I do not have this problem. About Features On Demand I'm not familiar yet and I can not help.
On this I do not know why I do not use either Office OneNote or Office 365 ProPlus (I use Office 2016) but I recommend keeping InputApp if you plan to use Metro Apps as it might be necessary for some Apps. Tablet PC is important for some devices and certain notebook models with touchscreen features so I keep this component for compatibility reasons.
I believe there are no issues with disabling Reserved Storage. Best not to disable the beep service and the Geolocation service if this is a manual service leave as is that it will only start when needed.

I do not know but if I am not mistaken this is necessary for Windows Mail as well.
I can not help because I have not tested 1903 yet. I think it's still very buggy. I did not have this problem with Search in 1809.
On Sandbox the problem may be because you are already in a virtualized environment (inside a VM).
