While you're kinda right quasi, the impact the US has on the rest of the world has greatly diminished over the past 20 years. The insular approach didn't start with Trump, it really started with Bush (and you could almost say "which Bush?" on that one) - Trump just popularized it and turned it into a catchcry. World markets have been moving away from US centric and US dollar for a very long time. It's certainly gained pace though in the past 4 years with an awful lot of countries just can't be arsed dealing with the crap that goes along with it. I'm certainly not saying there's no impact. Just that it's not what it once was.

I personally believe that it doesn't actually make much difference to the world if it's Trump or Biden, unless one of them starts a war. Trump is unhinged enough that it wouldn't shock me if such a thing happened. But it's not like a Democratic President hasn't ever done it, either. The question is "how big?" of a war and with whom. Australia is a very close ally, so no matter what we'd naturally follow. Our biggest trading partner, by far, is China (33% - the US is only 3%). Our economic growth depends on China's. So if the fight that's picked is between the US and China, we're pretty well fucked regardless. Then, so is the world.

As far as candidates go, I just don't see a difference between them. I'm sure there's some difference domestically; but again that doesn't matter to me. I certainly am a supporter of social services, public health etc; so the rolling back of any of those things, whilst it doesn't affect me, I consider the wrong thing to do as a human. US foreign policy just hasn't changed that much over the past 20 or 30 years, aside from getting more obnoxious. I can say as a person I find Trump repulsive. I know literally nothing at all about Biden though, I've basically never heard of him. Seems boring, but less of a wanker.

None of this, by the way, is any different to Australian politics. Either way, nobody standing for government are there to represent you or your interests. It's all about kicking back to their mates who get them into that position. So, I can definitely say "I don't care", because.. I don't care I just wish it'd hurry up and fuck off.
