FF I & FFII: Exist before the concept of summons was introduced.

FFIII, FFV, and the Tactics series: Utilize job systems where each character can be assigned 1 specific role. In some of these, a character can equip abilities learned on other jobs, but there are no canon combinations for any characters.

FFVI, FFVII, & FFVIII: Some characters share design elements from traditional jobs, but everyone is capable of learning general magic and summoning, and every character can fulfill whatever role you want them to.

FFXII: The original release shares similarities with VI, VII, and VIII where everyone can learn every general license, and the remaster is more like III, V, and the Tactics series where you assign a specific board to each character. In both versions, any party member can be taught to summon.

FXIII: Does not have anything that even resembles the jobs that the series is known for. Characters are defined by a combination of general RPG roles rather than specific, thematic jobs or classes, but every character has a personal summon.

FF Type-0: A more restrictive take on the VI, VII, and VIII system where magic and summoning is available to anyone, but the list of magic and summons is fairly shallow, and the majority of combat skills are defined by a character's personal, canon job.

FFXI: The other MMO where you can combine two jobs similarly to the III, V, and Tactics series example. There is no "canon" combination, but WHM is generally considered the best sub-job for SMN, though there are other options that offer different advantages, including SMN/NIN interestingly.

FFXV & FFXVI: Doesn't feature a job system, and characters don't quite resemble jobs from the series either. Summoning is exclusive to the protagonist.

This leaves only IV, IX, and X where summons have the opportunity to be crossed with another job canonically. Everything else either lets the player choose, doesn't have a summons or a job system, or everyone can summon, and in X's case, predetermined jobs are canonical, but the player can eventually teach each character everything, though this doesn't tend to happen until very late into the story or until postgame.

In these three, IV features a Summoner/Black Mage, IX features two Summoner/White Mages, and X has a Summoner/White Mage as well.
