Your Digikey link is malformed, it goes to the search page not results, but don't worry about it as your question is more general than you might think.
Just to give you an idea, I just scraped a common LCD monitor that had two CFL drivers that drove two tubes each. The output caps were rated at 3kv. I have no way to measure voltage that high but I would say that it would easily strike a 2kv tube.
Excessive strike voltage again isn't technically an issue, it's total energy in the strike that can kill a tube. I have four full sized tubes in my basement that all have black ends from old school bad fluorescent drivers (magnetic ballast with capacitor starters bypassed by arc tubes), they start up right away because of the high strike voltage, but the strike energy is too high so electrode vaporization kills the tube, this is why there's a urban myth about turning tube lights on and off causing great power usage than leaving them on all the time, which is not the case, excessive power cycling however will shorten tube life compared to continuous operation. I think there was a rule of thumb I heard once that if you're not going to be in the room for more than about 10 minutes that it's generally more cost effective to turn the lights off than leave them when comparing energy usage to tube life.
Modern driver designs are at least an order of magnitude better than even a couple years ago though so this issue is mitigated significantly.
