Absol is more fit with Ash, because:
1. Ash is always nice person with helping to problem pokemon, he have more experienced with pokemon tough personality (Charizard, Infernape, Incineroar (as a Litten), Lycanroc, Gengar)
2. Based on this preview look like Absol is strong and does not let anyone get close to someone, so I doubt Goh would have an easy time throwing pokeballs at him. Remember the capture episode of Galar Farfetch'd? So in this situation, Ash has a better chance because he can communicate with Pokemon.
3. Ash's Pokemon have different personalities, the team lacks a Pokemon with a unique silent personality similar to Ash's Grovyle - that why Absol is a perfect example.
Dragonite - a very positive and energetic pokemon, likes to hug someone.
Mimey - likes to clean rooms, but also to make fun of someone.
Gengar - likes to cause trouble to others.
Lucario - just like a ninja warrior.
Sirfetch'd - a very loyal knight.
Dracovish - a childish personality, a clever pokemon.
ABSOL - dark edgy lord?*
4. Ash specializes best in dark-type pokemon or pokemon with a dark movement set. Here are some examples:
Scraggy - dark/fighting pokemon
Krookodile - dark/ground pokemon (Bite and Crunch)
Greninja - water/dark pokemon
Incineroar - fire/dark pokemon
---------------------------------------------------
Totodile - water pokemon with Bite
Torterra - grass/ground with Bite (only when as a Turtwig)
Lycanroc - rock pokemon with Bite
Sirfetch'd - fighting pokemon with Night Slash, Brutal Swing
But i don't care if Goh will catch this pokemon, because i'm happy yet about Infernape return.
