Going to sell my company, then investing

Hey everyone, Posting this from a new anonymous account for privacy reasons and to avoid unsolicited personal messages. Hope you understand. I'm 29 years old, based in the Netherlands, expecting my first child, and I'm about to sell my e-commerce company. The expected proceeds are around €800k, which will sit in my holding company. From there, I want to invest it for the very long term, ideally 15-20 years. Some context about my situation: \\- My partner works 32 hours a week and will continue to do so \\- After the sale, I'll stay on for about a year to support the transition, with compensation \\- After that, I'll either freelance as an e-commerce specialist or take a job somewhere \\- We'll have steady income, so the invested money doesn't need to serve as a buffer \\- I own a home with a mortgage rate of 1.7%. paying it off early doesn't seem worth it \\- I already invest a small amount privately in a global ETF. Also read a lot about factor-investing what certainly appeals me too \\- Risk tolerance is high. I could handle a 30-40% drop without losing sleep \\- Preference: accumulating ETF, lump sum investment I'm not looking for financial advice, just curious what you would do. I'm already aware that WEBN and IWDA are the most obvious choices. No need to mention those. I'm specifically curious what you would pick outside of those two, or why you would or wouldn't go for them anyway. If I've forgotten anything relevant, please let me know in the comments. I'm curious to hear your thoughts!
