Much like books, that depends on what kind of stories interest you. Though it'd be advantageous for you if you enjoy romance, because that genre is heavily over-represented.
But if there are no titles that have already caught your interest, then my personal recommendation is to start with hybrid games such as VA-11 Hall-A, the Danganronpa series, the Ace Attorney series, WILL: A Wonderful World, and 999.
VNs are at their core a reading experience, frequently involving more words than what you'll find in the entire Lords of the Ring trilogy, but hybrid games like the above allow you to dip your toes in the VN genre without it purely being reading
Misericorde volumes 1 and 2 on Steam and Itch - both renpy based I believe. Fantastic example of an immersive novel, a murder mystery set in a 14th century abbey.
