I have found out that Normal and Fighting aren't my only least favourite types; I have an entire tier of least favourite types which includes the two mentioned above along with Dark, Ice, Grass and Rock. That said, from those types I like...
Dark: Sableye, Incineroar, Houndour, Houndoom (moreso its Mega), Johtonian Sneasel, Weavile, Greninja, Unovan Zorua (but not Zoroark) and Impidimp (but not its evolutions.)
Ice: Johtonian Sneasel (again), Weavile (again), Alolan Vulpix, Alolan Ninetales, Glastrier, Spheal, Sealeo (but not Walrein), Lapras, Kyurem.
Grass: Bulbasaur, Ivysaur (but NOT Venusaur), Budew, Roselia (but not Roserade as of late), the Cherubi line, the Chikorita line, the Applin line, Hisuian Voltorb (but not Electrode), Mow Rotom, the Phantump line, the Rowlet line, Dhelmise and regular Calyrex.
Rock: The Anorith line, the Tyrunt line, the Alolan Geodude line, the Rockruff line, Kleavor, Carbink, Diancie, Stakataka and Hisuian Growlithe (but not Arcanine).
That should be it.
