Recently I’ve been using airdrop to move videos from my iMac to my iPhone. They go straight into VLC and that works fine for me. If you use a PC not a Mac, I’m afraid I’ve no idea.
Google Drive/DropBox, or if you are OK with USB connection (as you've mentioned Image Capture), you can try iMazing. It's not syncing the device, so no data will be lost like with iTunes if this is your main concern.
