I'd use ethereum with a USDC token for anything that didn't need to be ethereum specifically. Then you're not subject to the volatility of the crypto itself, but still gain the ability to pay for things or transfer money globally. Unless you actually want the crypto exposure of course.
If you wanted stronger privacy, you could put the ethereum/usdc through Tornado Cash first. The SEC tried to sanction it and lost in court.
Also staying in USDC is easier for tax purposes.
