The myth is that a full frame mirrorless will do what the many other cameras could not: "this will help me take more pictures".
The reason people who have a whole bunch of cameras that they barely use are in that situation is that they see amazing photography in magazines and online, yet their photos fall far short of that. They refuse to accept that mirrorless or not, they're still not going to take amazing photographs, if they're not willing to climb a pretty steep learning curve, and take a lot of not-amazing photographs in the process. Watching 4 minute YouTubes of 10 simple things that will magically improve your photography doesn't count.
But for the camera manufacturers and the camera stores, this is a core customer set: the person who will come back and buy stuff hoping that the product hype will be their reality this time. Really, she should go back and look a the amazing photos that Canon said were taken with a t3i. Wow, those looked good!
Well, I have taken rather amazing photos with my T3i. Some of my best pictures ever were made in the 1960s with a Yashica rangefinder camera with a 45mm lens.
When I travel, I take my G7X II and leave my DSLRs and lenses at home. 13" x 19" prints from those trips grace the walls of my house. If I were advising her, I would suggest that camera or something similar, maybe one of the higher, but less pocketable, G models in her case.
My experiences with the camera department at this particular Best Buy have been very positive, more so than in any "real" camera store I have been in since 1975, say, or in other departments at Best Buy. They have people who shoot the brands they specialize in. Like my guy did, they defer to others in the department who know more about something than they do. He had sold me the 6D2 last year, and came over to ask how I was doing with it. Before the lady came over, that is what we were talking about. From comments here and in reviews, I had already planned to buy the 16-35mm f/4 around October unless some reason not to came along. After our conversation, I couldn't think of a good reason to wait. One of the reasons I stopped was to see if they had been able to maintain the department. Ladies with way too many cameras they don't use may help sustain it, to my benefit.
After my purchase, we talked about his advancing photography career and specifically about shooting interiors, since I was buying a SWA and he is getting a realtor for a client, and I had mentioned that I had done some work like that for friends in the business.
