FIDELITY CLEAN ENERGY ETF Stock Discussion

$FIDELITY CLEAN ENERGY ETF (FRNW.US)$ $FIDELITY CLOUD COMPUTING ETF (FCLD.US)$ $FIDELITY DIGITAL HEALTH ETF (FDHT.US)$ $FIDELITY ELECTRIC VEHICLES AND FUTURE TRANSPORTATION ETF (FDRV.US)$ I’m intrigued by Fidelity’s sexy new etf offerings: FRNW clean energy, FCLD cloud computing, FDHT digital health, FDRV electric vehicles… what do you guys think I should invest in for 1) an 18-month fund through spring 2023, and 2) 10+ year hold in my Roth? I’m very risk tolerant but I don’t want to pick individual stocks.
