I love historical and retro CC so one of my favorite sites is the Sims 4 History Challenge CC where all kinds of creators are linked and showcased.

There are also some Youtubers who like to showcase CC creators every month and link to their items. This way you get to see what they look like in game. Elliandra (almost same name as you!) does a lot of Maxis Match and is very relaxing to watch. Here's her best of 2021: https://www.youtube.com/watch?v=BY17oLKkg3U
My favorite MM hair creator is Birksche. She has a huge selection and has updated a bunch of her hairs here: https://birkschesoldstuff.wordpress.com/2021/08/04/updated-hairs-with-the-new-swatches/ just click on one and it will take you to the page with a picture of it and the download link.
