I used a lot of these in my Champions 1900 setting. Some others I used not yet mentioned:
Kung Fu original TV series
Space: 1889 rpg
Gotham By Gaslight comic
Jules Verne books
H.G. Wells books
Nadia: The Secret of Blue Water
Ann Rice’s Vampire Chronicles.
Things I MIGHT have used had they been around when I ran that campaign:
Kurt R.A. Giambastiani’s Cloudfall novels.
Tremors 4
Barbara Hambly’s Benjamin January mysteries novels*
Girl Genius comics
(There were other inspirations, but they wouldn‘t be helpful here.)
* not weird per se, but good stories with some nicely done fictionalization of New Orleans‘ historical culture and personalities
