I currently have two Canon APS-C cameras, and a number of lenses, some of which are APS-C and some are full-frame. Some of the lenses are Canon brand, but others are Tamron and Sigma lenses with Canon mounts. Question: Will the non-Canon lenses work on a Canon R or RP camera with the Canon adapter? I feel that theoretically they should, but also know that Canon might build a chip into the adapter to test for genuine Canon lenses.
Technically, the 3rd party should work. I believe in practice, it's hit n miss. You might consider why / if to retain cropped lenses, any brand, when considering an investment into a full-frame mirrorless body.
Some if not most of the features will work with those lenses. That said, I've read a few remarks about 3rd party lense not being 100% compatible. Things like slow focus or wrong or missing exif info for that lens.
My experience:
I have a Tokina 11-16 EF mount(but designed for Crop sensor) that vignettes severely from 11 to 15 mm, so if I keep it, it will be as a 16mm lens only. Rough Calculation, at 11 mm, the usable portion of the picture is approximately the equivalent of the 16 mm would deliver.
I also have a Sigma 18-250 that also shows vignetting out to about 70-100mm; so I am replacing two of my favorite lenses as I move to the EOS R body with the empty adapter
Canon EF lenses (true EF) work flawlessly, although I have a 70-300 that has difficulty keeping up with the EOS R's focussing speed, and it chatters at times
They work fine on my Canon RP. I have had any problems with my third party lenses.
I have a canon EOS R and tamron and sigma lenses I have works perfectly on the adapter.

I have used the Sigma 150-600C and the Tamron 18-400 with my R and adaptor with no problems. No problems with my Canon brand lenses using the R adaptor either.

Several of the non-Canon lenses are EF. In addition, I have a set of Kinko extension tubes and a Tamron teleconverter, which, while not actually lenses, will fit on an EF camera.
All of my third party lenses have worked without issue on my R.

They will work if you manually put the camera into crop mode. the R does that automatically for EF-S Canon lenses but not for third party. I think the resulting file is about 12MP or so.
If you do any 4K shooting they're worth keeping for that as the crop is really similar.
