It's amazing the scare stories that circulate on even well-informed forums.
Rapid charging: The ZOE ZE50 rapid charges its batteries at well under 1 C (that is a max charge rate / battery capacity) and uses its AC to cool the battery when necessary. And the charge rate is reduced dramatically as the battery charge level increases. The evidence that I can find on battery research indicates that there is no problem with charging at such a low charge rate. If you want to cover a lot of miles you don't have much option. There are many EV taxis around the world that have done huge mileages and only ever been rapid charged.
If the OP wants to add 80 miles range each week to a ZE50, requiring about 20 to 25 kWh, it takes about 20 minutes to add that at a 50kWh CCS charger, going from, for example, 20% to 70% SOC. I don't think doing that once a week will have any significant effect on battery life.
Charging to 100%: Battery research shows little damage to EV batteries by charging to 100% and then using the car. We always charged our ZE40 to 100% over three years and lost about 1% SOH per year, which I think is typical. The technical advice is not to leave your car with the battery sitting at 100% (or less than say 20%) for long periods. The ZOE (and most other EVs) leave top and bottom buffers unused so that users don't have to worry about it. Here's a relatively old video on the subject from a research scientist, rather than a journalist:
