Suggestions/ideas for a simple long-term buy and forget ETF-Growth-Portfolio

After discovering that trading stocks with margin is not a sustainable investing model I want to build a simple, yet effective portfolio for a longer time frame (10+ years)

My current plan would be to split my Portfolio into two equal parts:

1. A “low risk” All-World ETF (to always have a good night's sleep)

My current choice would be the iShares Core MSCI World UCITS ETF USD (Acc) IE00B4L5Y983

​

1. A “medium risk” but simple growth ETF

My current choice would be the iShares S&P 500 Information Technology Sector UCITS ETF USD (Acc) IE00B3WJKG14

However, I am also considering the Lyxor Nasdaq-100 UCITS ETF – Acc LU1829221024 for better “sector diversification” or the Xtrackers MSCI World Information Technology UCITS ETF 1C IE00BM67HT60 for a better “country diversification”

​

I am thankfully for your thoughts and recommendations
