"and even with focus peaking, the results are disappointing": Are you doing macro or close focus work and use Servo AF with AF "on"?
In that case maybe it is the problem I encountered with MF or one shot AF in macro / closeup at high apertures: After focusing I move a little bit and the distance between lens and object doesn't fit. With tripod you have "laboratory" conditions so "one shot MF" works well.
"One shot MF" is a source of unfocused images but after some trial and error I used the classical "move the camera along the optical axis"-technique and shutter was released when focus peaking was visible in the region of interest.
Just yesterday I put my M50 and the EF-M 32 @ f/1.4 in MF mode to find out, WHICH regions of the image will be sharp and it worked well. The object size was about 50 x 70mm so DOF was very thin.
One caveat of (Canons?) focus peaking is that it is only sensitive to vertical lines (in landscape orientation) - in my experience the quality of the focus peaking varies between different subjects.
Hopefully not too many trivial remarks - just my 2ct.
