France was the only country in Europe that practiced strict Salic law where the throne could not pass to a daughter nor through the female line. So how would France look if this hsdn't been the case and how would this have affected the other countries around that time? Would there even be a France?
Sorry but this assumption is just wrong.
Although it was not named Salic Law, in the HRE, and then in the German Confederacy that succeeded it in 1814, all the kingdom and electoral principalities had basically the same succession laws as France. Which is that when a king or prince has no male offspring, then his closest male relative on the older younger branch succeeds him even if he had daughters.
This is why, by exception, emperor Charles VI had to devise the pragmatic sanction for his elder daughter Maria Theresa could retain the Habsburg ancestral kingdom of Bohemia and other principalities.
This is why lateral male branches of the Wittelsbach succeeded to the elder branch in Rhine Palatinate and in Bavaria.
This is why Victoria of Great Britain did not become also queen of Hanover.
Now, to answer your question, if France had not decided to have only males of the continuous male branches to succeed to the throne, I think the first POD would be the 1322 succession, not the 1316 one.
Because in 1316, the question of gender was subsidiary.
The first arguments put forward by the future Philip V, then regent, and his supporters, to rule out his niece Joan of France/Navarre, was that she was too young and that there were doubts that she be the daughter of Louis X.
You can call it kind of a coup. But the point was that Philip V was the strong man of the family and that he had gathered enough support from those who either preferred him for his governing abilities or preferred him because they wanted stability and feared the uncertainty of having a young child (Joan was then but 5 years old and child mortality rate was terribly high even in the nobility) and of having a daughter who could but transmit the crown and kingly power to her still unknown future husband.
This being said, in 1322, no Salic Law means the successor of Philip V as king of France will be the Capetian duke Odo IV of Normandy (1295-1349), husband of Philip V’s elder daughter Joan (1308-1347)
They had only one child, Philip (1323-1346), who died just before his parents.
This will probably be butterflied away by Odo and Joan’s access to the royal throne of France. Because this Philip would then be heir to the royal throne and, as such, will probably not directly participate in the fights of the feudal war in which he was OTL deadly wounded.
The other point which will be butterflied away is this Philip’s marriage. As future king of France, he will marry someone else than OTL Joan of Auvergne. And you can then make it like you want. Either they have many children. Or they have but one child who dies young (like OTL Philip of Rouvres) and this opens a new succession crisis.
But what it will change is that the duchy of Burgundy, the county of Burgundy, and the county of Artois will become part of the royal domain. Which OTL happened only 150 to 350 years later.
And the Royal branch of the Capetians will probably get Flanders by the late 14th century.
Massive change which makes France more powerful than it already was and which probably butterflies away the rivalry and then civil war with the too powerful OTL second Capetian House of Burgundy.
