Ok ok ok. I'm also a photographer; I was using a 2006 MacPro until about Spring 2020, when it was clear the machine was no longer practical (I was having to use a Windows PC to convert camera RAW to dng files, as my Mac just couldn't do it). The OS was too old to accept Lr updates, etc. So I bought a 2012 MacMini as a 'stopgap', as the rumoured M.x machines still hadn't appeared. This at least allowed the latest OS at the time (Catalina), and allowed for an up to date Lr version, which meant I could import images directly from my camera. The MacMini had 16Gb RAM. I then finally bought a 2021 M1 iMac in August that year, with 16Gb memory.
Now. Lr is a memory hog, I find, and the worst app for sucking up that lovely unified memory. However, as I'm not the kind of person to try to run umpteen apps simultaneously, or have 500+ browser tabs going, this is never an issue. I tend to work on one thing at a time, then move onto the next task. But unless you're the kind of person to want to run Lr, Ps, Ai, render video FX and process multi-layered audio at the same time, then 16GB is plenty. I actually know two other people who run Lr on 8Gb machines, so it can be done with less.
I will caveat this by saying that my image files are 24Mp, so between 35-50Mb each. If you are dealing with much higher Mp files, then more RAM might be advisable, I don't know. Lr deals with my camera files quickly and without fuss. I can also do stuff like photo-merging focus stacked (macro) images in Ps, so many tens, hundreds of separate full-sized images at once. And the odd bit of 4k video, some fairly basic audio with a few layers, stuff like that. My iMac is perfect for me, anyway, and way more capable than the machine it replaced.
You see? Experience beats theory every time, for me.
As for storage; 14Tb is a LOT; I'm only on about 5Tb for 23 years of Mac ownership (only been doing photography seriously for like the last 10 though), although I'm not a 'machine gunner'. My files are stored on multiple HDDs in various enclosures/NAS type things in various locations, and I use a G-Raid Thunderbolt 3 Raid 0 drive for immediate storage. This isn't as quick as I'd like, though, so I want to get a 2Tb or so SSD for 'current projects'.
