Plug it in via USB, and then most Android devices show up as USB sticks within Windows Explorer. You can access the filesystem the same way you'd access any external media, and drag & drop photos over.
Apple, however, in their infinite wisdom made MacOS pop open iTunes when you connect an iPhone as a USB device. You can "import" them into Photos (another Apple walled garden), but they don't show up as a filesystem, and you can't use normal filesystem operations or terminal commands to move them over.
I know it's not ideal, but if you have iCloud disabled in Photos.app, use that to download photos from your phone to Photos.app, then in Photos.app, select all, and export to your chosen location, then delete from Photos.app. I know it's a few more steps, but this might make it easier than selecting 10+ files to AirDrop. There might be a way to automate that with the shortcuts app. I haven't looked yet. I hope this doesn't come across as "you're holding it wrong", that wasn't my intent.
