If you want to grow quickly, I recommend focusing on TikTok. Record your videos from the front with a good camera, create several clips, and upload them to TikTok with subtitles. Then, from TikTok, direct viewers to your YouTube channel where you'll have your full-length video.

Alternatively, you can upload your full-length video to YouTube and simultaneously upload your synchronized clips to YouTube Shorts, Instagram, and TikTok, and then do the same thing: direct viewers to your full-length video.
