Gold investment - best way?

Can someone please guide me what will be the best way to invest in gold, ruling out the physical gold bars?

Endowus seems to have funds focusing on gold mining - doesn’t meet my objective for pure gold

Saxo traders - I can find USA GOLD ETFs here but I have never invested in ETFs or commodities and a bit confused as it’s asking me margins and duration (day order, one week, one month etc.)

I just want to buy electronic gold, appreciate if someone can make it easy for me, sorry about the dumb questions
