On iPhone, I'm using Google Photo as my primary photo backup.

Anyone would have a good solution to backup iPhone/iOS files/photos to any cloud (s3, blazer, nas, etc..), NAS, or computer that just work?

Use OneDrive. Photo backup works in the most "dumb" possible manner, just by dumping every photo as a file into a big folder. And you can pretty seamlessly use it as file storage in lieu of iCloud. And it's absurdly cheap, you get 1TB (+ more if you're willing to create multiple accounts) with O365, along with Word/Excel.

I use photosync to photoprism and it works great

I toss my phone on the wireless charger and it auto uploads them.

Best part is unlike trapping my photos in Google or Apple they are just files stored on a disk
