You delete things you don't need or use to free up space. That includes deleting photos, apps, music, files, email, messages, etc. See this for help --> Manage storage on iPhone - Apple Support

Finally, you own an iPhone 8, which is rapidly heading towards being an obsolete device. You clearly don't own an iPhone which meets your storage needs. With all new iPhone 17 model phones, the minimum storage option is 256GB. Perhaps it's time to consider retiring your pretty old at this point iPhone and buy a new, more modern iPhone.
