I use this app: https://play.google.com/store/apps/details?id=com.brunosousa.pokeinfo
It's got a pokédex with stats, learnset, possible evolutions, if a move is physical/special and at which level it learns what move
Unbound has a few changes from the normal ones so it's not 100% exact but You can have a rough outline of a Pokémon capabilities by doing a little bit of research
Another thing that may help is https://pokemonshowdown.com/
You can build teams, experiment with any Pokémon You would like, any moveset and stat configuration, and test them against other players
