At least, on an iPhone running iOS 12.1.4, you can share photos in several different ways. Yes, you can use Apple Photos, or you can use Image Capture.app (in the Applications folder on all Macs), and download the original. OR, you can *email* it at one of four sizes (not JPEG MB, but the all-important actual pixel dimensions).
From an iPhone 7 Plus, these email attachments are labeled Small (240x320 pixels), Medium (480x640 pixels), Large (1512x2016 pixels), and Actual Size (3024x4032 pixels). These are capable of making prints *at 240 PPI minimum print resolution* at the following sizes: Small = 1x1.33 inches; Medium = 2x2.67 inches; Large = 6.3x8.4 inches; Actual Size = 12.6x16.8 inches. In my experience, only the Actual Size image is worth using.

iPhone image quality can be quite good when the light is good. Low light imagery suffers from heavy noise reduction smearing, but for most snapshot purposes, it's acceptable.
I've attached a typical night scene (my twins at a mini-golf place in Florida over Christmas break). I cropped and downsized it in Photoshop, adding +7 Clarity in ACR and converting to sRGB from iPhone's native profile (Display P3). All other parameters are as they were, straight out of the iPhone 7 Plus. It makes a very decent 8x10.
