The US stock market outperforms any European or Canadian stock market in the past 10 years, and there's no reason that won't continue. This is because the US is where tech stocks are listed.
So, invest in the US even if you live outside the US. YMMV.
Not only is historical performance no guarantee of future performance, 10 years is a pretty short time span to look back - it doesn't even take you back to the '08 recession. The US did well in the 1990s and 2010s, but both ex-US developed markets and emerging markets did better in the 2000s: https://www.ishares.com/us/strategies/international-etfs
It's good to diversify internationally, and that probably does mean holding some US equities ETF even if you're in Europe. As for what else to buy, this may be a good starting point: https://www.lynalden.com/best-etfs/
