FYI.... Canon makes their own CMOS sensors, and have done so since around 2000 or 2001 (everyone else continued using CCD until 2006-2008).
Sony also makes their own CMOS sensors... as well as almost everyone elses'. Nikon and Pentax outsource their sensors from Sony. So there shouldn't be very much difference in color rendition. There may be some variance straight out of the camera due to differences in firmware, processing and way each manufacturer "tunes" their camera... but the
potential color rendition should be very similar (lenses might make more difference).

I may rent the Sony A7iii and try it before I move ahead.
That's probably a very good idea. You might compare it to the Canon 6D Mark II, too.

Yes, they do. Nikon also can be switched to APS-C mode. But....
1. That's no difference from simply cropping an image from those or any other full frame camera in post-processing. Exact same result.
2. Resolution takes a huge hit:
- What remains might be "enough" with the 42MP A7RIII ($2800)... in APS-C mode it produces 18MP images.
- It's probably not with the 24MP A7III ($2000)... in APS-C mode all that remains is about 10MP.
Compare to the 20MP of your APS-C 70D or the 24MP of your SL2.
There was a lot of talk about this going on, so we did a head-to-head comparison years ago: 21MP Canon 5D Mark II full frame versus an 18MP Canon 7D APS-C.... shooting the same subject from the same distance using the same lens under carefully controlled conditions (tripod, manual focusing using Live View magnification, mirror lockup, etc.)... then cropping the FF image down to match the APS-C. The result was that the APS-C image was very obviously superior... after all, it was still 18MP, while the cropped image from the FF camera was around 8MP.
IMO the "APS-C modes" simply aren't all that useful. You can do the same with a simple crop in post... And there's significant loss of image quality when it's done with anything other than the very high resolution FF cameras (42MP Sony, 46MP Nikon, 50MP Canon). Give it a try... but be prepared for disappointment.
