Possibly. I'm not too clued up on the French electoral system. I believe it's quite complicated. I know a lot of candidates voluntarily dropped out as well, in order to help the vote against the far right. I don't know if a coalition is possible but I understand they're rare.
The New Populat Front is already a grand coalition for the sake of the election. There's big differences In it as regards Ukraine and the agreement before the election may not hold. The standing aside with members of the Ensemble Alliance was nor really a coalition, and I'm not sure they can work together. The Ensemble is an odd party
Held together by power rather than ideology but many in it hate groups within the NPF.
I'd regard myself as better informed than average on the French elections as an outsider but that's not saying much. The huge rise in seats for National Rally makes me think that they have achieved all they need for next time if the multiple coalitions don't work.
Macron as French President has to me more powers than makes sense in a balanced constitution and he can take some actions in the future that the NR were talking about stopping, though it's not clear had they wom a majority that they could.
I guess it's more of watch this space.
