does it bring any advantages over https://metacpan.org/pod/DBD::CSV? (not being perl is not an advantage).

Well, DBD::CSV is just a driver for DBI, not a command that is "unix pipeline friendly"... So there's that.

Perl is pipeline friendly though ...

DBD::CSV is a library, which you could use to build a command, but doesn't seem to come with one out of the box. q is just a command, but not a library.

One could use DBI + DBD::CSV + Perl to build something similar to q, but that's a batteries not included solution.
