If you can, also run electrs ( https://github.com/romanz/electrs )and tor proxy (usually via a systemd unit) and then sparrow wallet will connect into electrs via tor.
Then once you have electrs up and running via tor you can also connect Phoenix wallet and Bluewallet to your electrs instance.
Map: tor -> electrs -> bitcoin core
