Thanks for the purchase! For the framerate there is no "recommanded" one, since it depends of the gamefeel that you want in your game :)
For example for a fightgame, I'll focus on a very fast framerate but I'll make the keypose freeze (to add more contrast into the animations and make it more dynamic). At the opposite if it's a "chill" game, I'll try to have a quite low framerate and have a unique framerate to keep it chill.
So in the end, it depends of your game and the gamefeel you want :) The best way to know is to test and also check examples of games that you like and see what was their way to play with framerate :)
