Same pathway as me for Souls games, enjoy it brother! It wont click for everyone, but if it does, the crack will flow, as you discovered in DS3
Have you played any others, like Demon's Souls, and DS1/2?
Edit oops, missed your last paragraph. You're in for a treat with Demon's, but def play DS1 too, goat tier lore and level design, just far slower than DS3
I think DS3 is the perfect combo of all Soulsborne games, gameplay wise. DS1/BB are tops for atmosphere/lore/level design IMO, even DS2 is fascinating lore wise (insane amount of content too), at least the Sins remaster.
Sekiro never did it for me though, but you might love it.
