Raid setup recommendations - eviltoast

Hey all, just purchased a new NAS, Synology 8-bay, full of 6TB drives. I don’t want to debate the Synology OS vs something like TrueNAS or similar OS. What RAID would you setup the drives with? Raid 5, Raid 6, something different? Looking for a nice balance between available space, speed and recovery in the event of something fails. I will be mostly be storing media (videos etc) family photos etc. Anything critical will be replicated to a remote NAS and Google drive.

What do you recommend

Thanks
