Thank you @rosemow ! That means I'll keep the no culling in McCommand active and cull manually.

I think McCommand Center mod has an option to unhide all hidden households, but that's forever, so you cannot hide them again. Hidden households include the deceased, grim reaper, Jasmine Holiday and maybe others I do not remember at the moment.
You can get your dead back by keeping their urns around, waiting for them to haunt and invite them into your household as playable ghosts. Or, if the relationship is too low, there's a mod that lets you move them in regardless (testingcheats should be able to accomplish that, too).
Sims that die off lot or in households other than your currently active one do not leave an urn. They are still in the game files (until they get culles, that is, so it's a short timeframe). But they sometimes join clubs generated by the game and can be met again this way (The game only generates clubs if you have less than eleven, though).
