There are some genres I'm consistently good at, there are some I'm consistently bad at, and there are some where it really, really depends on the game itself.
I'm TERRIBLE at RTS games. I can be good at macro or good at micro, but pursuing multiple goals is really hard for me. Also, I have a really bad tendency to get into a sunk cost mindset and avoid changing up my strategy.
I'm pretty good at fighting games, adventure games (who isn't), and
I'm very good at almost every RPG I've ever played.
As for shooters, it really depends on the game. I can regularly lead my team in TF2 and I'm pretty good at essentially all the classes (though I almost never play pyro). I do at least decently in most modern-combat-style shooters (though I don't play them enough to really get good, my baseline skill isn't bad at all). But I am embarassingly bad at a lot of other shooters and, while I love playing shooter campaigns on really high difficulty, it typically involves a horrendous amount of save scumming. This is somehow especially true of FPSRPGs which is unfortunately probably my favourite subgenre.
My problem is that I like all of these genres, even the ones I'm really bad at. Luckily, a lot of them are single-player, but it's frustrating that I can't really play RTS games with my friends (most of whom are unnaturally talented at the genre).
But you don't want to see me with a fighting or racing game.
