nino_xo There's a theme called BoosterTheme. check out their website which lists all its features. it claims to have almost all the necessary apps inbuilt in the theme itself (included in coding). You can visit a demo store and check how it looks and how it performs (check on mobile and desktop both, its customized for both at the same time).
If you like it, I have one license, as I do buy for clients but sometimes things won't work as we plan so I have one spare to give.
I have ample experience working on themes if you want I can help you to install and/or guide you for any changes or customization you may want for your store.
