Hello Confusing_2023,
Your post indicates that your device is running iOS 14, is that correct? If you're using iOS 13, please check out the information in the following link, which will guide you through how to clear Other storage on your iPhone, and may be helpful: Clear Other storage on your iPhone or iPad
Clear Other storage on your iPhone or iPad
If you have iOS or iPadOS 13, your iPhone or iPad storage is full, and the storage is mostly taken up by "Other" storage, update your device to iOS or iPadOS 13.6.1 or later.
Update your device
An issue in iOS or iPadOS 13 might prevent the system from freeing up storage for you. To fix this issue, update your iPhone or iPad to iOS or iPadOS 13.6.1 or later.
If you don’t have enough available storage to update wirelessly, update your device to iOS or iPadOS 14.1 or later using a computer.

About cached files in "Other"
The Finder and iTunes categorize cached music, videos, and photos as Other instead of actual songs, videos, or photos. Cached files are created when you stream or view content like music, videos, and photos. When you stream music or video, that content is stored as cached files on your device so you can quickly access it again.
Your device automatically removes cached files and temporary files when your device needs more space.
