If you want a pils style beer, Jever Fun is pretty hoppy. Krombacher has a decent 0.0 beer as well. A bit on the sweet side for me but I have that sometimes. I also recall seeing a beer that was labelled as Feinherb at some point that was pretty tasty. The exact name escapes me.
Several of the Bavarian beer hall style helles beers now also come in alcohol free versions. Very drinkable. They taste very similar. Bayreuther is one that you might find in some shops.
Many of the Hefeweizen varieties also exist in alcohol free versions and are pretty drinkable. Most places will have that available.
Not German but some bars now have Guinness 0.0 in cans. Haven't seen that in the supermarket but it's a near drop in replacement for normal Guinness as far as I'm concerned and I tend to order that when I see it available.
I stopped drinking alcohol a few years ago but I still enjoy going out with friends who do drink. Mostly people barely notice what other people drink. And the lack of a hangover after a good night sleep is a nice bonus. Although you can overdo it. I always joke about all of the downsides of drinking beers without any of the upsides.
I'd also like to add Weihenstephaner Hefeweißbier Alkoholfrei is fantastic: https://www.weihenstephaner.de/en/our-beers/non-alcoholic-wh...
From what I understand Weihenstephaner developed a unique brewing process which results in a great tasting 0% beer with only 15 calories per 100 ml.
I also like their Helles Alkoholfrei: https://www.weihenstephaner.de/en/our-beers/non-alcoholic-or...
If you like pilsner, I do enjoy an occasional Kulmbacher Edelherb.
The Augustiner Helles Alkoholfrei is incredibly popular, but hard to come by even here in Bavaria.
Similarly popular and among my favorites is the Bayreuther Hell Alkoholfrei.
That being said, neither of these options is available at Lidl or Aldi in Germany, so I would assume they aren‘t internationally either.
