I so wish I can give you a perspective that doesn't go too far out of the Pagan realm of seeing things. I see my ancestors
and spirits as deities (or people I give reverence to); but I don't worship them (they aren't god/s). They are very real rather than allegory, and if I choose a pantheon for them it would be any indigenous faith with whom shamanism and like practices are affiliated (noting what
@Quintessence said). They are literal (I'll focus on spirits) in that they interact with us on a physical not just a internal or experiential level. They
are the intuitions we get and the gut feelings which some say come from psychology, but I believe the cause is
spirit -ual as well. They (spirits/deities/the departed) are not who we bow down to but, as
@Nietzsche says, "they're our family; You don't lower yourself for anything or anyone. You honour them on your own terms."
If I used word worship, it would be interchangeable with reverence not submission. Thereby the Spirits and the departed (relations or not)
are deities.
As for specific pantheons, I don't hear many Pagans view their deities as beliefs either. Most I read here see them as very real and no belief is required for deities who they interact with on a daily basis.
