Pokécardex has been very helpful for me, I use that to track my cards in general as well as a 2nd account to track my dex binder cards.
@circlehunter has a great topic with his haunter list google doc for both English and Japanese. CircleHunter's Haunter Collection
I only collect English as a master set and my list was basically the same as his.
Only thing I can add is for cameo’s (if you are interested in that) I have used this reddit post https://www.reddit.com/r/PokemonTCG/comments/11tak3z/my_cameo_artwork_database_has_been_updated_for/ which is a list of cameo’s for all pokemon.
