Mind sharing your mod list? I don't even know where to begin searching for these kinds of mods.
If you asked me 2 days ago I would gladly make a list, but right now I'm very far from my computer and I won't be back home soon, sorry. Also, I didn't played the game since the Horse Ranch expansion, I don't know what's up to date anymore.
BUT, the core mod that no one should play Sims 4 without is MCCC, "The MC Command Center". It has A TON of options and offer great control over a lot of shit in the game. From the top of my head: you can invert the alien pregnancy (only female sims gets pregnant from male aliens), you can forbid pieces of clothing for auto-generated sims, you can make everyone 100% straight (or gay), you can mess with teen pregnancy, you can filter out the stupid bar nights, you can edit any sim you see (click on a sim walking around and edit their name, clothes, etc.), and, by far, one of the best options: you can make the game generate townies only from your gallery.
I recommend downloading it from the official site:
https://deaderpool-mccc.com/index.html , if you download from another place it might be out-of-date or missing a module.
Another tip: before using the "townies from your gallery" option on a clean save, make a sim in Sulani, walk around for 5 minutes and travel to Selvadorada - again, walking around the plaza for 5 minutes. That way, the native townies of both places will be correctly generated, and you don't end up with a pale vampire damsel from your gallery being a tropical forest native. Do this in any neighborhood you want the default townies to spawn before activating that option.
