Do you think it would be better to run the full node over VPN + Tor?
You should never run VPN together with Tor for anything, including for Bitcoin node.
Running BTC node with Tor only is used a lot and it works perfectly fine for purpose of hiding your real IP address.
Or can you run the node over the clearnet without fear?
Running Tor, VPN or Bitcoin node can be interpreted as suspicious behavior in some countries, so don't ask other people if you should fear something.
