37F, €180k to invest, retiring at ~60. simple ETF portfolio?

Profile:
• 37 years old
• €180k to invest now
• Time horizon: ~23 years
• Goal: retire around 60
• Based in Europe, using IBKR
• Prefers simple, low-maintenance investing (no stock picking, no active trading)

Current idea:
• 100% VWCE (global equities)
or
• 80% VWCE / 20% global bonds (EUR hedged)

Questions:

1. With ~23 years horizon, does adding bonds now make sense or just reduces returns unnecessarily?
2. Is sticking to 1–2 ETFs optimal here, or would you structure it differently?
3. Any major risks or blind spots in this setup (sequence risk, allocation, etc.)?

Looking for a simple, robust long-term approach. Not interested in complex portfolios.

thanks
