S5ii / S5iiX for professional photography?

I’m considering getting an S5ii or S5iix for full time commercial photography (product photos, interiors, and the occasional portrait, proposal or wedding for family/friends). Also would like to use for video/hybrid coverage occasionally.

Is the autofocus and image quality good or reliable enough for a pro? I currently have an SL3 and would like something that’s faster and more reliable and figured the S5ii would be nice since I already own L mount glass.
