Excellent, but...

Camera was bought specifically for travel. It has all the customisable features I require, including resolution, but is seriously let down by the poor quality of lenses by Canon, particularly the zoom range.

11-22 is fine, sigma 16mm is excellent, 22mm is fine, 32mm is excellent, sigma 30mm is very good, sigma 56mm is excellent.

So, that is quite i nice lens selection, however, to your point, an as good as the M6mkII standard zoom (that is: better than the 15-45 and 18-150mm) is missing. And there are reasons it's missing:

- a good standard zoom is going to be bigger than the typical ef-m size

There is a significant difference between bigger and huge.  The Panasonic 12-60mm f/3.5-6.6 and Fuji 18-55mm f/2.8-4.0 are two examples of standard kit lenses that are far better optically than than the EF-M alternatives while still being relatively compact.

- if it's going to be big anyway, what not adapt ef or ef-s glass

The problem is there are not really good alternatives for adapting either.  The closest option is the EF-S 17-55mm f/2.8 IS, but that lens has problems too.

If you want great zooms IQ on your M6mkII you should accept the weight and go with the adapted sigma f/1.8 zooms (18-35 and 50-100mm). The 32mm and 56mm primes are a tad better, but on crop cameras these zooms are beating all the other lenses in their focal range (maybe save the fulll frame sigma 85mm Art).

Even with the shorter focal range, that 18-35mm is the same size as a full frame 24-70mm f/2.8 lens.  The Sigma also lack stabilization.  For a travel lens for the OP, the RP with the EF 24-105mm f/4 would be a far better option than that Sigma on the M6 II.

Canon’s hype for this camera is therefore misleading, if not downright false. This means I’m unable to write anything too positive about the camera ‘cause I’ve yet to discover its real potential for taking high quality photographs!

You can't blame a manufacturer they don't break the laws of physics. Good zooms aren't small, so there's no reason to make one specifically for the ef-m mount. Good zooms are big. If you accept big you can adapt.

Fixing massive quality control issues does not require the laws a physics to be broken.
