Mac Mini M4 Pro memory for Lightroom & Photoshop

My experience with those two apps in the past, especially if both are open at the same time, buy as much RAM as you can possibly afford!

I have had sessions where those two apps can quickly gobble up 16 GB or more in a short session and I was not even working with massive files.

One prime reason to max out the RAM is to avoid disk swapping. With something like the MacMini Pro, the tight integration of the SSD and unified memory and the speed will not really show that much of a slowdown when it takes place. The downside is that it will add wear to the SSD.

The other reason for getting as much RAM as you can afford at purchase is that you cannot upgrade the RAM after purchase as it is integrated on the "M" series chips.

Look at tests on YouTube where many have stressed the Mac Mini M4 Pro. It never seems to have an issue with the 24Gb of Ram. You be the judge

I would suggest you get as much memory as your budget allows. It can't be expanded later, and high-end graphics software generally prefers lots of RAM for best performance. If budget is tight, you can cut down the size of the internal storage (though I would not recommend less than 512GB) since you can always use an external drive for more document space and that's usually less expensive per-gigabyte than Apple's internal storage pricing.
