Cable tidy for desk top - quality and hole size?

I'm now trying to source some nice round cable tidy fittings to go into the bespoke desk top.
First issue is that there are so many very similar products. <(Amazon.com product link shortened) B0050GEOU6> How to tell which are good quality and which are not? Price doesn't seem to be an absolute guide.
Second issue, hole size. The majority seem to be listed as 60mm (80mm also available). However in the detail some say that they are 56 or 58.8mm diameter and others say that they are 60mm diameter for the insert part that passes through the desk. Many don't even give dimensions. Some are more detailed than others. <(Amazon.com product link shortened) B0752NJY2S/> is notable because it supplies a detailed table for dimensions.
Hole size is important to get a snug fit. I assume that you look for a cutter very slightly smaller than the diameter of the fitting (and assume that the hole will be a little bigger than the nominal diameter of the cutter) or you look for a fitting which has plastic lugs/fins which ensure a snug fit in slightly larger holes.
Either way, the standard range of cutters doesn't seem to match the 60mm/80mm fittings. <https://www.screwfix.com/c/tools/holesaws/cat5920018#category t5920018>
57mm or 64mm
76mm or 79mm or 86mm.
Anyway, has anyone used this kind of fitting, and if so are there any recommendations of supplier/brand?
Cheers

By looking at the customer reviews with a pinch of salt.

It never is.

Yeah, often a problem with amazon and aliexpress.
