There are multiple standards when it comes to photo metadata. EXIF is one type, IPTC IIM/Legacy is another, and then XMP (which includes IPTC Core/Ext).

Most of the data in the EXIF block is data from the camera that created the image, though there are a few others that do get added by other software, such as Artist and Copyright. Anything that is in the IPTC IIM block is almost certainly data added at a later point, as I don't believe there is a camera that writes this data. Amost any XMP data is also data that was added later, though some more modern cameras do save the regions recognized as faces in XMP.

The examples you list above are almost certainly all part of the EXIF block and data from the camera. Whether they are important to you is your decision. If you think there is some point where you will get really serious about knowing how your images were shot, then they should be saved. But unless they are RAW images of some type (CR2, NEF, ARW, DNG, etc), then the existence or removal of that data won't affect the image. Never remove EXIF data from a RAW image as that will probably permanently corrupt the image.

Additional blocks you might find would be the MakerNotes, which is basically more advanced EXIF data, specific to each individual camera type. Also there is the possibility of an ICC Profile, though that usually comes from editing an image. The ICC profile should not be removed as it will affect the colors of an image.
