Now that I have finished installing GrapheneOS on my Google Pixel, what kind of apps shall I install? FOSS only?

I haven't installed Google play services and don't think I will (it will get sandboxed right? Is there real harm?)

What about closed source software? Do you recommend installing them or just stick to FOSS?
