We could say digital gold is btc alternatives. But bitcoin has no physical asset and consist only of digital but has immensely got some fair value. If you would noticed both are limited in supply like btc max supply only to 21million while gold is a naturally occuring mineral which also can be conserved as thr process of producing is limited to countries potential resources. If this in the future got depleted more, imagine its price value due to scarce. The only difference of two are its use case which gold preserve more advantages since it can backed up some currency such as US unlike btc which still got some issues.
Perhaps, it would be a great idea for bitcoin to be backed by gold to make sure that the value of bitcoin will be strong enough. Though both are having similarities in characters such as scarcity, gold could not be directly compared to bitcoin but we could think of it as an alternative to the digital world. In the end, I still consider gold as more valuable when fiat money system breaks because it is tangible, and this characteristic is what makes it solely different from bitcoin.
Going back to OP:
The digital gold use case is often referred to as Bitcoins core value proposition, so a closer correlation with physical gold could indicate a greater level of understanding and acceptance of this point from market participants. Additionally, the introduction of central bank-issued digital currencies could clarify the value proposition of something like Bitcoin in the minds of the general public.
