I continue to use Photos once in a while. It still compares well, in my view with any of the raw processors on the Mac -- including ACR/LR -- with 'auto' settings that are really very good.
I typically process photos first in DXO "Optics Pro for Photos" (the App Store, about $10, I think) which offers lens corrections, noise reduction and 'dehaze', then use several of the settings in the Photos "Adjust" panels (WB, light, curves, definition, color). The whole process takes about a minute with more than acceptable results. I rarely feel the need for local adjustments on-top. But if I do then I tend to use Luminar 3 that has a Photos-plugin or Raw Power which has fine controls. If local adjustments are needed (eg. to remove lens/sensor smudges) I use the "Pixelmator Retouch" plugin for photos (comes with Pixelmator).
I agree with you, however, that printing is too primitive to use in Photos. Apple is interested only in selling you a print-on-demand service. I have, however, exported full-size TIFFs to LR using an "auto import" folder: LR imports whatever is there into its catalog with configurable name-settings etc (see the LR Classic "File" menu). The advantages of LR printing are the use of ICC profiles for your paper, LR export-for-print sharpening etc.
What puzzles me still about the Photos environment is the nature of the data that is passed between photos and the "plug-ins". Photos itself is a 'non-destructive' editor (with full restoration of the raw image available at any time from the Photos database). But I am not sure what the plugins are working on. I think most are also working in a non-destructive fashion but I find it difficult to believe that e.g. DXO Optics Pro for Photos applies its "Prime" noise reduction non-destructively. Still, I can't find any evidence of full-size duplicate versions in the .photolibrary folder. There are 'masters' (the original raws) and there are XMP files in an 'Attachments' folder. All the other data seems to be database-related including a number of JPEG copies of the images.
Here are a couple of images (before & after) that I processed in about 40 seconds using Photos and the DXO Optics Pro plugin (including lens corrections for my OLY 7-14mm , 'smart lighting' and 'Prime' noise reduction). Not a brilliant photo but the processing rescued one where the dynamic range of the raw was much greater than it appeared.
