Sorry folks, I’m still home nursing a nasty chest cold and my only tool today is an iPad.
I have failed to get the postgresql.conf into the copy buffer so that, along with the results of pg_settings, will have to wait for another day.
Today there are “only” 135 Mar 16 WAL files. I haven’t sorted out which have been cleaned up but can do so if that’s thought to be helpful.
There is still 2.2G in the pg_wal directory but that disc has ~360G left. (I believe the burst of WAL files was the result of a novice using LIMIT with a to-Json function and the target table has >100M rows.)
Given that current WALs come and go regularly, I think the CHECKPOINT is running frequently enough (for normal loads at least).

Two more have been cleaned up. 001C and 001D generated at 16:38 Mar 16SELECT * FROM pg_settings;has someone in the past configured wal archiving?You've ran out of disk space as this log message you shared states:No space left on devicewhat's the output of df -h--BTW , how spread apart are checkpoints happening? do you have stats on that? maybe they're too spread apart and that's why WAL files cannot be recycled rapidly enough?--
