Yes. And yes. And from the bottom of all my Sims hearts, yes. I want more Occults. I *need* more Occults.
Elves, Fairies/Dryads, Werewolves, Half-Dragons, Ghosts, Shade (this version, an unlucky cursed Sim that is a physical shadow and need light to not wither away to nothing, can regain power by sleeping in a special empty painting complete with lamps, can be cured) and if possible, Half-Giants. (the last one would probably be forced to remain outside of houses to not break anything, so... yeah, not the best idea.
More Occults comes in my hopeful top 3, occults, romance interactions and generations. I'd even enjoy if our currents Occults would be improved. More Mermaid powers, reactions to aliens, vampires and spellcasters, and a bonus acceptance trait at least for spellcasters. My sim has throwing spells around for a year now, my other sims need to stop asking themselves if this is magic.
