Depends on what you want to do with it...

One thing I'd recommend is using Tor for node connections (it's a setting -- you just have to turn it on) and then turn off the other options (e.g. clearnet connections).

I'd also recommend setting up Electrs and Mempool (so you can leverage some of the benefits of having your own Node).

Then grab a copy of Sparrow wallet and learn how to connect that to your node...

Those I'd say are good basic next steps...
