Typically, I just describe the sound I hear in their in-game cry or use an appropriate sound based on the kind of creature a Pokemon is based on.
Scraggy has a high-pitched trill or chirp, while Scrafty's cry in comparison is more of a warble mixed with a croak. Murkrow has a raspy or dry squawk, Floette whistle sharply, Vibrava emotes with the harsh buzz of its wings, Lairon's roars echo with a metallic twang, Donphan trumpets with its long trunk, Tauros bellows and moos, et cetera. Some Pokemon have special cries, like Gallade, whose cry is a terse grunt followed by the audible sharpness of its tonfa blades extending from its elbows. If a Pokemon has had their cry put to text, I'll occasionally throw that in as a reference. Zoroark saying "Kwaaan," for instance like it does in BW2, but for the most part I try to avoid giving Pokemon direct quotes.
A Pokemon can't speak, but it still needs to be understood, through body language--the tilt of its head, the flick of its tail or the stamping of its foot, the highs and lows of its voice. In this way, it encourages the author to be more creative with their prose and I feel lends a certain maturity and immersion to the writing. The anime cries by contrast just shunt me out of the narrative because I'm reminded of the anime instead of whatever's going on in the scene, but that's a personal problem.
