It could help, yes.
For the best privacy, you could have Tor only outgoing and incoming connections in you Bitcoin node.
Since it's easier to do an isolation attack to Tor only nodes (see https://arxiv.org/pdf/1410.6079), you might want to have also some "clearnet" connections as well.
For outgoing connections with privacy, you could use a VPN.
For incoming connections, you could use Blindport Port service to have a pair of public IPs and a port do advertise for incoming connections that would get routed to your node. Without the world knowing your residential IP.
Another option is to use Blindport IP where you would have a public IP just for you that you can use for incoming and outgoing traffic.

This is probably a dumb question, but does Blindport give one the ability to host a public node from their home in a more private manner?
