Codenames
Choose Codenames when you have even teams and people who like a little competition. It is a bad pick for three people, and a bad pick if only one person is willing to give clues.
Both are word games that finish quickly. The social shape is different, and that is the whole decision.
Codenames, designed by Vlaada Chvátil and published in 2015, is a team game of one-word clues, about 15 minutes. It won the 2016 Spiel des Jahres. Just One, designed by Ludovic Roudy and Bruno Sautter and published in 2018, is cooperative for 3–7 players, about 20 minutes. Everyone writes a one-word clue, and duplicate clues are removed. It won the 2019 Spiel des Jahres.
Codenames wants a clue-giver who enjoys the pressure and a team that will not mind being wrong in public. Just One wants a table that can laugh when two people wrote the same word and both clues vanish. If anyone is anxious about performing, Just One is the kinder room.
Choose Codenames when you have even teams and people who like a little competition. It is a bad pick for three people, and a bad pick if only one person is willing to give clues.
Choose Just One when the group is mixed, small, or tired of games that make one person the performer. You need at least three. The rules fit on the table talk you are already having.

Both use vocabulary. Early readers will struggle as the clue-giver in Codenames. Just One can work if an adult writes for a child, but then it is a different game. Check the box age against your actual table.
Neither is a two-player game. Codenames: Duet is a separate cooperative box. Use the two-player list on this site if the party is really a pair.
