What is the difference and the significance for the check commands that are names with prefixes
"check_xi_serice_" versus names with prfixes "check_"?

Here are some examples:

check_xi_service_tcp and check_tcp
check_xi_service_ftp and check_ftp
check_xi_service_http and check_http



thanks,

The backend commands for these are what's important and besides the tcp check, they take the same argument format. This is likely just historical hold over from Core and either command should work from XI.

When I create my website URL services using check_xi_service_http to monitor remote URL, it gives me HTTP 500 error, but once I change the service to use the command check_http, then it works fine.

It is possible that the commands may have been edited(Configure > Core Config Manager > Commands > _Commands) . Verify the back end command and arguments configured there for each.

Also, use the Run Check Command button to run the check with the different names selected, and post the results(remove anything sensitive).
