Want to invest, what stocks, etfs to buy

Hello! Yes, I'm asking that... I'm not as much educated in this field as I would like to be (learning by day) but I want to make money with money on the side that I don't use. I'm from Europe, inflation in my country is around 2,5% but it will get worse. I did some trades that were good, for example I bought Rolls Royce last year and it did 100%+. But I have stocks that are -20% like Microsoft and so on. My trades are just in hundreds of $. (around 400$ invested...) So my question is, are there any safe options now? I don't have much time to watch the market... I heard that ASTS is not bad, but that's probably late to join. Looked at some ETFs but I'm not sure. Safest option is ofc probably SnP500. I don't need +1000% in months, I would like something that would outperform the SnP500 (and inflation ofc). I'm not making much money but I want to invest so in the future I might have some money... Ofc if there are articles, studies that can help me choose (learn), link them (or share your strategies/stocks hehe). Need advice and a little shitpost, thank you all in advance, take it with reserve.
