Perhaps you might enjoy making cocktail yourselves :D
There is /r/Mocktails, imbibe magazine has a alcohol free section with a lot of recipes, and there are books as well - I'd suggest good drinks by Julia Bainbridge and Zero by alinea group-.
My biggest pain point is that there is no high end past Zero. The Julia book is solid.
In actual cocktails, there are a handful of books that are _incredible_ and cater to high end cocktails. I have ~600 bottles at home (I know...) and I really appreciate those books. I'm willing to make cranberry tequila rosemary ice. Or clarify a punch.
Almost every mocktail resource is... quite frankly... too simple. "Add lemon to fake sparking wine to make a delicious French 75!"
This makes sense from sheer numbers. Way less folks making mocktails. I love that Alinea book. Just wish there were good websites out there.
I've started doing spirit free cocktails recently, but I definitely get that there are way less resources than regular cocktails. However, zero has a section on making backbar alcohols such that you might be able to use them on regular cocktails, by substituting the alcohol with their spirit free version. The taste won't be the same of course, and you might have to alter the dosage, but it's better than nothing. Perhaps you won't be able to clarify an alcohol free wine, but I'm sure there are recipes that aren't ruined by replacing alcohol with its non alcoholic version

The nyc special and the change of address are pretty nice imho
