Out the top of my head, Futoku no Guild (lewd)? It had videogames and modern tech, even if everyone went around fighting with the standard litRPG weapon thing.
I think Ningen Fushin had idols of all things, but it was still mostly medieval tech.
The Executioner and Her Way of Life had magitech trains and I think it was like victorian tech. Not exactly monster hunting but there was a whole thing about killing people from other worlds.
Archmage had a magic train, but no other technology going on so far.

Don't think you need to research though. Most of these just use them as dressing and the rest is rather standard as far as storytelling goes. Maybe stories set in modern age would be a better reference to what you need.
