I don't believe things will go that far, and the reason they were shut down is that they enhance privacy for BTC users, and we all know the government is targeting any service that enhances privacy, by charging them for allowing money launderers conceal their tx's. So Electrum and some of the services you mentioned do not fall under this category, because they do not enhance privacy or make it hard to track BTC tx's.
Electrum is just a wallet that does not violate any laws that could allow the government to pay attention to it. There are no prohibited functions in it, only the most necessary things to receive and send bitcoins, also can hold there, but for this it is better to use a hardware wallet.
I was thinking about the sparrow, it has some kind of mixing function, although I have never used it enough, so I am well versed in all its capabilities. I just use an Electrum bundle with a hardware wallet and it seems to me that this is enough to safely store my btc.
