Don't get a G7X II for macro. They are not very useful for that. In every other way they absolutely trounce the old G series, but they can't do macro.
I've been gathering that about the G7X II, though some say if you fiddle with it you can get good results. ,...
About the only thing that can be done to improve OOC JPG corner/ edge sharpness is to stop the lens down to smaller aperture; but if stopped down too far the overall image quality sharpness will be reduced from diffraction. Depending upon RAW app used, may be able to get better results PP RAW images.
Other issue is the G7 X / G7 X II, like other 1"-Type sensor compacts, in keeping lens/ camera size small the lens image circle does not cover the corners of the sensor ...

... hence corner sharpness softness due to in-camera JPG PP/ lens corrections. For more info and images on this see my post HERE as to similar issue with the FZ1000.
You need to take the time and read several full reviews on the G7 X II; e.g., DPR HERE, and Imaging Resource HERE.
The Imaging Resource's "Canon G7X Mark II Optics" section does a detail review of the
G7 X II's lens performance, e.g.:

The majority of the 1"-Type sensor compacts closest focus distance around 1.97" (see HERE) at the WA setting. The thing to note is the 1.97" is the distance between the object and the sensor surface -- hence the front of lens is going to be quite close to the object.
Following a note DPR has included in with G7 X II Review and other 1"-Type sensor camera reviews:

A Note on Lens Quality
Something we've noticed while testing all of the 1"-type enthusiast compacts is a large amount of variation in lens quality.
In this case, we have one G7 X II that's soft in the corners but great in the center and another that's just the opposite. The lenses on our original G7 Xs as well as a pair of G5 Xs weren't great, either. But this isn't a Canon problem alone. Of our four Sony RX100 IV cameras, three have so-so lenses and one is stellar. But then three of our four RX100 III copies have very good lenses. In other words, your mileage may vary.
Given the ambitious nature of the lenses on these cameras it's not surprising that there's a lot of variation. While you might find a copy that's sharp corner-to-corner, odds are that you won't, but that's the nature of the beast.
***********************************************************
Nothing is simple anymore....
At least now days with various online sites like DPR, Imagining Resource, etc. providing full reviews with full size sample images, one CAN find/ learn enough info on a camera. And for items that one does not fully understand can post questions in this and/ or other forums to get help.
Cheers,
