Good luck with your money, personally I will choose gold over fiat as the best option. Unlike fiat which will be under the pressure of inflation, gold will protect our money from inflation in long term that's why when there are many negative about a country like a war, bank collapse, etc. people will tend to move their fiat money to gold or other instruments.
There is nothing wrong if you choose to save gold instead of Fiat for the several reasons you mentioned, but you should also know that the price of gold also has the potential to fall at any time, even if only in a very small size. I also like to store gold instead of fiat, but I also like to store other assets like land and Bitcoin because those two things are also good enough to keep the value of the money we have.
Even though Bitcoin sometimes drops in price, when Bitcoin becomes harder to find, the price will also increase rapidly. Apart from that, you still have to use bank services for the rest of your life even though you won't be saving more money in it and one more thing I think it would be better to also save some important assets rather than just keeping one of them for now.
