Replying myself (because it will save someone else life in the future)
I enabled the network debug and noticed these IOB suspicious "warning" msg:
devif_poll: WARNING: IOB Prepare failed for dev wlan0!
Then after some investigation I just changed the IOB Throttle from 0 to:
CONFIG_IOB_THROTTLE=12
It was enough to make FTP client work again:
Sat Jan 7 13:15:28 2023 [pid 132850] [ftpclient] FTP response: Client
"::ffff:192.168.0.2", "229 Entering Extended Passive Mode (|||42678|)"

"::ffff:192.168.0.2", "/files/test.bin", 1048576 bytes, 2.38Kbyte/sec
Sat Jan 7 13:22:37 2023 [pid 132850] [ftpclient] FTP response: Client
"::ffff:192.168.0.2", "226 Transfer complete."
The network speed for ESP32 seems a little bit low, but it is another chapter.
