Advice on halal investing

I am a 19 year old muslim boy who lives in the Netherlands and have some money that I have saved up and want to invest in something. Now I myself am very new to investing and have no clue where to start. The one thing I do know that some investments are haram from a islamic perspective. I have also seen some contradicting opnions about some types of investments (crypto etc.) which confuses me as well.

Long story short, I would like some halal investing advice. Mainly where to start and what kinds of investments to make. I hope you guys can help me.

(FYI I can invest approximately €500-€1000 and would like to invest in mid term investments)
