So, do I need to run vacuum freeze on those tables? Also, if
autovacuum_freeze_max_age is commented, does it still mean that the

Yes, and unless you're running a very high transaction rate you probably don't need to mess with it. Likewise you normally don't need to explicitly freeze, though it's not a bad idea to do so after a large data load. Just make sure that there's no open transactions that were started before the data load transaction when you run the VACUUM.
