Sorry I am late in coming to the party.

I share your experience in using movie recording in R5C. I am still trying to get the best optimal setting for movie recording in video AF.

So far, I have tried the following:

1) Turned off face and eye detect. This function can make R5C struggles to focus if >10-15 metres away or at shorter distance.. perhaps eye detect is only good for interview.

2) Used large or whole area, selectable..

3) continuous AF

4) Tracking ---when find AF

5) Rent and try video AF with 3rd party prime with EF/AF adaptor. I found AF in video with sigma art prime is much faster than my RF 50 f.12 prime wide open at equivalent distance and definitely much faster than RF zoom at 10-20 feet away. I have not tried long 3rd party prime (like 300 f2.8) as I have only been shooting indoors. This is purely my own non scientific testing. Please try it yourself before getting your own copy.

6) Yes, R5 AF in movie is much better. You can turn on in body and optical stabilisation with 100-500 hand held and get decent movie recording.

Did you change AF speed and response settings?
2) I have the opposite experience, I find the large area not really useful, either the small or whole.

6) As I own both R5 and R5c and on point 6 it makes no difference on how stable it is, actually sometime with the 100-500 on the R5 you get some big jumps due to IBIS that I don't get on the R5c. So for handled video 100-500 I find it better on the R5c. I do use it a lot of handhelds video. Btw is known that IBIS is not really particularly effective on long focal lengths.

Wonderful to hear your experience with R5C in movie shooting:

Condition I have tested the lenses in is of dim indoor light, requiring Iso 1280 to 6400 and at lens maximal aperture--- 1.2, 1.4 or 2.8 with stationary non human subjects at different distances and face/eye detect off.

AF speed and response is maximal -- +2 or +3.

I found the small area AF least able to log on focus and could hunt even achieving focus. In continuous AF, it could lose focus after few seconds into recording. I have to use button 1 (AF-ON) to expedite the initial focus and then use tracking (configure to button 13) to lock on focus. Small area AF frame became a problem if human subjects were 20 to 30 feet away and standing at slight angle to the RF zoom instead of facing the lens. It is not a problem for R5C with small area AF and face/eye detect on if the subjects (5-10) are 10-20 feet away facing the RF zoom lens face on in reasonable lighting.

R5C AF is more problematic if the subject is moving. For example, the hands of a pianist in action-- R5C will struggle but R5 can still achieve focus most of the time.

I have a near disastrous shoot for an event due to R5C AF several weeks ago. I sent the footage to Canon as I am not certain it was not a hardware problem. Canon initial response was asking for camera serial number as they suspected it was a firmware problem.

My solution to the r5C AF problem to date is Sigma prime (with adaptor). I have found the 35 f1.4 and 40 f 1.4 can achieve focus far quicker than RF zoom. Initially I thought it was an unfair comparison between prime vs RF zoom. However, I notice the RF 50 f1.2 prime has the same AF problem.

Interesting point about R5 and 100-500 zoom. I did shoot an event handheld with both Optical and IBS turned on and the footage was perfect. I was sitting down at the time and not panning.
