Where are you from? Where are you going? Can’t really give you advice without knowing those things.
As a general rule: don’t expect perfection. Some things will suck, and if you go in expecting everything to be perfect you’ll be disappointed. Also, wherever you go is still a normal place, filled with normal people, living normal lives. Don’t be a nuisance to the locals, and don’t expect/demand anyone not working in hospitality to go out of their way on your behalf (and even people working in hospitality, the “the customer is always right” mentality isn’t a thing everywhere).
We clearly live in different bubbles because this is the first time I’ve seen someone refer to MacOS as “very mainstream”. iOS, sure, but I haven’t seen many Macs out in the wild. It’s certainly not common to the point where people would expect MacOS behaviour as the default.
The UFP has a currency - Federation Credits. The average citizen may not need (or even have) money, but it exists and is presumably accessible in some way if you have genuine need. For example the station personnel on DS9 never had issues paying at Quark’s, so one can assume that they did get a salary because they were posted to a capitalist environment. I’d assume that child support would work on a similar “as needed” basis.
Firefox. Librewolf’s defaults make it very inconvenient to use as a normal, day to day web browser. You can obviously change all of that but at that point you might as well just use Firefox with a handful of add-ons so that’s what I’m doing.
This dude has been full mask off since Covid. And he’s been an asshole before too, I think the façade really started to crack when he was told that his mini submarine was useless (of course one could argue that the fact that the first thing Musk’s mind went to when he wanted to disparage someone was “paedo” is rather telling).
