I would like to ask for advice on what camera to purchase next. Perhaps some background would help. Twenty years ago I sold my Nikon manual film SLR and began to use point-and-shoot digitals. My two most recent cameras were a Sony NEX-3, and, for the last 4-5 years, a Sony RX100 IV. The aim was minimal weight and bulk, with acceptable image quality; and I'm happy enough with the Sony's 24-70mm (35 mm equivalent) zoom range. I almost exclusively shoot jpegs, editing some of those. I take some issue with the color of the Sony's out-of-camera jpegs; have decided I want higher IQ and more dial controls; and am willing to accept somewhat more bulk and weight. Probably would only purchase a few lenses. Am considering the following cameras: Fujifilm XT-30 or possibly XT-3, Canon M6 II, Nikon Z50 (APS-C); or Canon RP, Nikon Z5, Sony A7 II (full frame). Would most likely start out with a modest zoom, and would like to initially stay closer to $1K than $2K if possible. Notice I'm looking for compactness within those categories; and wondering if I really need to go to full frame.

Any opinions would be most appreciated.
