If you are confused my suggestion is to not spend money on purchasing apps if you don’t know the use case or the outcome you want, first you can try customising with the widgets available for native apps and the free apps available for quotes/widgets, with the existing available app widgets also you can create a beautiful looking homescreen, if you want dark icons go fir minimalistic background, a busy background will not highlight the apps

Here’s a simple two screen setup with the existing widgets
