The greatest begginer camera

Hello photographers for reddit. I'm looking for a camera that can be a creative tool. Something that I can use for photo and video. If you could find something under $300-400 USED that would be great! Keep in mind im a broke high schooler lol.

Requirements: 4k 30 fps, 4k photos, some sort of LOG shooting

Nice to haves (in order of niceness): Stabilization (i hate shaky videos), some sort of built in "feel" or color profiles that will give my phots a unique look, and an EVF for photos.

Thank youuuuu

EDIT: Yeah I'm a bit dense so keep in mind I'm going more video heavy than photo heavy. That being said, I don't want it to shoot photos like a potato

EDIT EDIT: Yeah I was trying to get everything for nothing. So assuming I can save up, is the canon r50 a good option?
