Where can I find an example one to set up specific items for this bitcoin node I have setup?
If you've downloaded the tarball from bitcoin core's website,
there should be a sample 713-line bitcoin.conf in it that contains instructions and commented configs with explanations of what can it do.
Just extract it and you'll find the sample conf inside "
bitcoin-31.0" dir where you extracted the file.
Just uncomment the ones that you need.
Of course, that file wont work if it's left there instead of moving it to your datadir.
