Not taking it personally, :-) I 100% understand why you might also prefer it the other way. The weird "some apps save it to Photos while others save it to Files" situation is a consequence of Files being a relatively late addition to the iOS ecosystem. A lot of apps are poorly maintained, use some cross platform framework that doesn't support the Files feature well, or the developers are simply unaware of the distinction. It will probably get better over time. One thing Apple could do in the mean time is to also expose Photos as a folder view inside of Files (they do this on macOS, to some extent, on the file pickers. I've never actually used it) Re: Transferring it to a PC, the one thing that won't work is the seamless copy and paste via handoff. You can plug in a USB stick into an iPad or iPhone (using an adapter for pre-15 models, or if the USB stick is USB-A) formatted as exFAT and it should just work. AFAIK, there isn't a single button to delete all photos, probably to avoid people doing it accidentally. You'll need to manually select all photos and hit delete. Or you can also write a small script via the Shortcuts app to delete them for you.
