I'm going back to Canon realm after years of frustration waiting for Nikon to catch up on things, so here I am back on the boat.

I know the R5 is best for wildlife, but given that I mainly photograph wildlife, I prefer a crop sensor.

I understand as I believe is to be correct the R7 is a replacement for the 7DMark II?

I'm reaching out here to determine if the R7 is in fact adequate enough for photographing fast moving objects in terms of tracking and autofocus.

That depends on the lens and the ambient light (as well as the contrast of the subject).  The R7 has the hardest time seeing AF in low light out of all the recent Canon R-series bodies, but the R7 is also giving far more pixels-on-subject with the same lens, so if you decide that the light is too poor for the R7 to focus quickly then you could also use a faster, shorter lens or remove a TC to get adequate focus speed and just save the "pixels on subject" feature for when light is better.

My impression with the R5 and R7 is that with the same subject, poor lighting, and optics is that the R5 acquires focus faster, but if you put a 1.4x TC on the R5 to get the same pixels-on-subject as the R7, then the R5 AF is a little bit slower than the R7 AF.
