I would personally say Bitcoin. Bitcoin is currently in demand. Many different companies are constantly investing in Bitcoin. At present its price is 45 thousand, in future it will not take more than 1-2 lakh.
Many? How much? You probably can't name a dozen of them without looking at google. You saw Microstrategy and Tesla buying BTC and that's probably all you know about. So "many" companies turn out to be 3 or 4.
Did you know that there are more companies demanding gold than companies demanding BTC? Gold is not only for the jewelry industry.
In fact, Gold has more use cases than BTC. What can you do with BTC? Not much, only speculating or hold, and if you want to spend it you most of the time need to exchange it for vouchers or fiat or something else done with a 3rd party.
Gold can be used in the pharma industry, electronics, jewelry, dentistry, architecture, aerospace...
Still the main use of gold is for jewelry, and it's questionable whether gold will be in demand in this industry.
And I disagree on "only speculating or hold".
Many of us here, including you, receive payments in BTC. Receiving payments in fiat currencies would be much more complicated.
