Canon supports ‘adapted’ lens better than Sony supports native lenses. Many Sony lenses are limited to 10-15 FPS or less. All 3rd party E mount lens are limited to 10-15 FPS. Sony has several restrictions for 3rd party ‘native’ lenses.

Once again many Canon adapted lenses work better than Sony native lenses. So these Isn’t really a native lens advantage because Canon has more and often better EF lenses.

Frames per second is far from the top of my list when picking a lens. Number one  and two AF speed and accuracy and of course image quality.

Also I am not sure anymore if I consider an EF lens an adapted lens for Canon anymore. The R body series and lens mount were designed from the beginning to maintain compatibility with the EF mount and Canon's own lenses. That was a great strategy and I can tell from my EF lenses I still and use on my R5.

I am not as sure how third party EF lenses do with the adaption but I would think that depends more on how the EF version worked in the first place. I know some 3rd party lenses were less than stellar in the first place. I had to abandon the first Sigma Art lenses I bought (35 and 50) because I couldn't get them to focus accurately on my 5D Mark III. Sigma did fix this issue but it was not a Canon problem.
