The s&p500 is 100% us focused, if you’re looking for some diversity (some of the tech companies you’re buying might be covered in the s&p500 fund) then you could try adding some of what you’ve mentioned.
It depends on how engaged you want to be, if you want to buy and forget then I’d go for a global tracker like VWRL or EGMW.
If however you wanted to learn more then this thread, while a little in the weeds at times, is as good a thing as I can think of.
