Good luck with your surgery, Chuck.
I've run Dell Precision laptops for a long time with various flavors of Linux. Like you, I greatly prefer a 17 inch screen, but those things are usually quite heavy; I still own an M6500, two M6700s, and a 7740. The Precision 7740, while slimmer than the other 17's, is still a heavyweight, nearly reaching 7 pounds. The old Ruger M77 Mk II Ultra Light bolt action rifle, chambered in .270 Winchester, that I used to own years ago, was lighter than the 7740, by about a quarter pound. (Kicked like crazy, too)
Was recently given a System 76 Lemur Pro 10, and getting used to the relatively tiny screen was a big adjustment. I use GNOME, and installed the package that allows display scaling; scaled 125% it's usable. The Lemur Pro 10 is manufactured by Clevo, the same company that does a lot of the higher end Dell, HP, and other laptops. It is almost too light; I would have preferred a bit more metal and a little less plastic, but it's passable. And it was a gift, so I'm pleased as punch with it in that regard.
Debian Bookworm, of course, and it just works.
So I think you did really well with the XPS 13; hope it gives you good and reliable service, especially for this purpose.
