Postscript from my previous posts above:
I ended up going mirrorless and getting an EOS RP. Compared with my 2007-vintage Rebel XT, this thing has a bewildering array of features!...I am still getting used to the menus. The body proportions take some getting used to, but the pivoting display is handy. The battery life is less than stellar, as was widely reported in reviews, but I have two extra batteries and it has been good enough for what I do. The RP seems to lack a RAW+JPEG shooting mode (I haven't delved deeply for it but I can't find it), which was initially annoying but I've just switched to shooting RAW and will get over it.
My overarching requirement was for a full-frame sensor camera, and the RP is that.
