I use Google Photos. It's easy to upload photos from the app on my phone. The app uses some sort of algorithm to figure out if photos need to be rotated and it's pretty accurate at this. Also it has some facial recognition features, so that makes it easy to find a collection of photos of the same person. Access control is also available and personally I have chosen to make all photos private, but I do have an album of my baby that I frequently update. This album I share with some family members. AFAIK people don't need to sign up to Google to see the photos when using a share link, but not 100% sure - how this works with access control, I am not entirely sure.
