I originally chose to make my account on lemmy.world since all the content seemed to come from there. But I’ve since learned that I can fill my feed with stuff from any instance so it feels like it doesn’t actually matter if I’m on lemmy.world or not. At the same time, Lemmy.world seems to be frequently under attack so I’m wondering if I should change instance but have no idea what I should even be looking for when choosing.

You could try here, it lists the uptime and geo location of plenty of fedi instances of all stripes. Take the uptimes with a grain of salt though, if they can’t reach an instance for whatever reason it gets marked down even if it was actually fine, so it can read a bit low sometimes.
