> I strongly recommend those magnetic USB connectors

Note that these connectors are in violation of USB standard and potentially harmful as they expose the pins in an unintended way. For instance, notice that all the connection on the USB port are not all the same length, it is a form of protection, to make sure the power lines are well connected before the data lines make contact. With magnetic USB connectors, you lose that feature, in addition to potential issues with ESD, short circuits, etc...

I have a friend who swears by them and never had a problem, but still, that's good to know.

This was noticeable on USB-A connectors when you look closely where the two outside pins were slightly longer than the two inside pins: the Make-First, Break-Last (MFBL) principle. You can also see the same thing on SATA edge connector pins.

The ~2015 Macbook Magsafe 2 connector had 2 slightly longer spring pins (two pins furthest from centre). See https://ir.ozone.ru/s3/multimedia-3/wc500/6020365815.jpg

Take care googling for photos because many are CAD mockups misinform (because they are drawn pretty incorrectly and show no physical length differences).

USB-C does have longer pins for the ground, and the CC (configuration channel) connects last. A USB-C host doesn't deliver power until it is negotiated using the CC pins.

So USB-C via a "magsafe" connector is safe.

But maybe look for the two outermost pins to be longer.

You mention ESD which could be riskier since charged fingers or worse could touch contacts directly. However the lip around the contacts is usually grounded so any spark should be grounded first. I would also assume modern electronics are well protected against ESD (nobody wants occasional undiagnosable failures leading to refunds). Sure that stuff from earlier this century wasn't so well protected. YMMV if you are a sparky person in a sparky environs: weigh the downside costs of different approaches appropriately.

You want to get everything grounded before the data wires connect. But that's more about the shroud than the pins as far as I understand it, and a magnetic connector could ensure grounding if it was designed to do so. And for charging purposes you could skip the data wires entirely.
