Thank you, This was very helpful and I got it. I did unset the db_create_file_dest on both databases. I found that the db_file_name_convert had not been set on the standby, so I set it and that worked. I appreciate the quick help!

You need to UNSET db_create_file_dest on the standby as it overrides db_file_name_convert. DB_FILE_NAME_CONVERT will get ignored.
DB_CREATE_FILE_DEST will also create oracle managed file names (OMF filenames) as you see getting done in your example.
Then you need to make sure your DB_FILE_NAME_CONVERT parameter is set CORRECTLY to properly place the datafile in the right place.
So on db_file_name_convert should be something like:
IF primary location = /oracle/data/DGRDTSTD/DGRDTSTD/datafile
Then db_file_name_convert on standby should be:
db_file_name_convert=' DGRDTSTD/DGRDTSTD',' DGRDTSTC/DGRDTSTC' ;
Your db_file_name_convert must properly set the full string you want to replace with the string you want to use as the replacement value.

We’ve set up data guard with a primary and a secondary. The primary is DGRDTSTD. The secondary is DGRDTSTC. We are running Oracle 19c on Linux Red Hat 7.
If I create a new data file on the primary, it creates it on the secondary, but in the wrong directory. It creates a new directory, called DGRDTSTD and puts the new file there, instead of putting it in the DGRDTSTC directory. I can move it and rename it, but I shouldn’t have to.
I tried to set the db_create_file_dest parameter on both databases:
on the standby:
alter system set db_create_file_dest='/oracle/data/DGRDTSTC';
on the primary:
alter system set db_create_file_dest='/oracle/data/DGRDTSTD';
All that did was to create the new file as:
/oracle/data/DGRDTSTC/DGRDTSTC/datafile/o1_mf_test_dat_jj2xgght_.dbf
