I have had experience with some of the pistols on your wishlist. The Caniks that I have shot at the ADSS demo bay have been the full-size pistols. They have been well built and functional. They had acceptable grip angles. However, I really don't know if I could find a use for a Canik.
Last year, at the ADSS demo bay I had the opportunity to shoot a 43X and a 48. I found these pistols to be snappier than my P365s, I think because of the grip angle.
Virtually all of my handguns (except for one or two) are used in some form of competition. I try to shoot: NRA 2700, GSSF, ShootSig, and USPSA. I tend to use my P365 and P320 in the ShootSig, my Shield Plus Performance Center in USPSA, and (obviously) my Glocks in GSSF. My carry is either a P365 or P365-380, both with the metallic sights. I trust irons over optics, since I've shot irons for almost 55 years.
My caution would be directed towards the S&W Shield family. In particular, I've read that the optic cut on many of the Shield Pluses is angled to mostly accommodate the Crimson Trace optics (owned by S&W, the last that I heard). I've read more than I want of owners having to either recut the optics cut or purchase an adapter plate so their pistol would zero with the optic.
Personally, as much as I like my Shield Plus, I'd lean more to the Sig P365 Micro.
