Nothing wrong with wrenching an older Eurobike if that’s your thing, I just think a new rider should have something reliable such that they’re not worried about the bike when learning to ride.
That implies that the european bikes aren’t reliable. That hasn’t been my personal observation and just like with european cars, I believe it is a reputation that is undeserved and is mostly created by folks with little or no experience with them. I will however say that if a dealership is required for service then the Italian options might not be a good choice. The dealerships are few and far between while the Japanese and American brands have a shop in every town.
I feel that any new bike (when I say new I mean things built in the last 20 years) should be more than reliable enough for even the most novice of rider with minimal mechanical knowledge, provided that the bike purchased wasn’t a POS to begin with. I haven’t had the need to do anything to any modern bike I’ve owned aside from the most basic maintenance.
