I've followed รve Antonov for a while. She's a booktuber and I really enjoy her content. She doesn't yell at you in front of the camera. Not overwhelming at all and has a medium speed to her speech. Her 10 best reads from 2024 video is linked above.
Maryam Gadery's YouTube channel consists of giving advice, inspirational talks, etc. not my favorite type of content but she speaks clearly, slowly and puts subtitles to her videos in French. It's helpful. Has been really useful for my listening skills.
I love her YouTube videos. Her vlogs are consistent in style and storytelling. So satisfying to watch. I particularly love her series Abroad Diaries (linked above)
