As I understand it, the commerical WinZip and the free 7z both use a
decent implementation of AES256 - so are viable provided you pick (and
can communicate out of band) a decent password. KDF on both is 1K
iterations (for compatibility) but it is worth noting 7z had a poor PRNG
for its IV generator prior to v19 (2019-02-22) so worth upgrading if older.
The original pkzip algo is worse than useless, of course :)
