The eGolf is a bit meh IMO, the small battery and fact it's not making the most of the interior space etc would make it a bit compromised..
However, plenty of early 2020/2021 ID.3's with the 58KWh battery with ~50k miles.. for £13k.. even if the battery is 90% (cars on there with 70k miles are at 88%, most of that would be lost in the first 10-20K miles) at that point, that's still a WLTP of 240 miles vs the best case 184 of the eGolf..
The '1st edition' ones are good, they came with better lights etc, although even the base spec 'Life' as adaptive cruise, heated seats etc.. but if you want full LED active lights etc, then you want a higher spec.
The ID.3 is a better proposition for the suspension, interior space, charging speeds, etc, and the batteries are proving reliable (bar that recall for faulty modules, but that is sorted at their expense!).
