I'm not sure the US would fall immediately into the French bloc as proposed. Assuming roughly the same ending to the American Revolution, the largest trading partner with the US was still Great Britain, and continued to be for quite a few decades after independence. In fact both the Washington and Adams administrations were quite friendly towards Britain, and while Jefferson was more oriented towards the French, it wasn't the French markets that were buying up US goods, it was still mainly Britain and the Dutch.
This actually puts the US in an awkward position of wanting to thread the needle between the two continental blocs, further, assuming Washington still exists, his advocacy to "avoid foreign entanglements" was still fresh in everyone's mind, so you might see the US trying to play the neutral party between the British and French led blocs, especially as to the US neither side is actually a "bad guy" ideologically (as with the proposed timeline you functionally have a Anglo-Liberal* Britain, and Anglo-Liberal US, and a Anglo-Liberal France thus meaning that the Scottish Enlightenment and the Anglo-American Liberal tradition has completely displaced the Continental Liberal tradition). That said, the addition of the Spanish with the French bloc, and a stronger Spain able to hold onto it's American colonies, might be able to build a strong enough economic bloc to swing the majority of trade from the US to them over Britain.
I can't speak for the thought process of others, but my thinking here is that with France ending up more similar to the Americans ideologically, the opponents of Franco-American alliance will have rather less "ammunition". In OTL, the revolutionary French diplomats quickly made trouble, outright trying to spead Jacobinism in America. This behaviour annoyed Washington personally, I seem to recall. Moreover, the excesses in France allowed the Federalists to dismiss the Jeffersonians as "Jacobins" who'd surely introduce their own reign of terror. (Jefferson's Francophilia and occasionally
very 'revolutionary' statements made him an easy target.) It was also a bit troubling that the French
monarchy had helped the USA in its struggle for independence, and was now overthrown-- a problem compounded by the fact that the Jacobins turned on Lafayette. Not to mention the XYZ affair...
Things would be quite different if the "French revolution" is instead a much more moderated palace coup that introduces liberalism (in the same tradition that also informed the American revolution) as the king's policy and sees the commanders who aided the Americans raised to prominent positions. The (alt-)Jeffersonians would have the wind in their sails, politically. Unlike in OTL,
their accusations aimed at the Federalists (specifically that they were crypto-tories) would be the louder voices, not drowned out by the OTL yell of "Jacobin! Jacobin!"
Add to this a number of familiar and beloved friends of the USA high in the French government and/or military, plus the fact that without the incompetent and corrupt gaggle of loons that ran OTL Revolutionary France even getting in charge, there's no XYZ affair to cause trouble... Well. I'd imagine the (alt-)Jeffersonians winning the Presidency when Washington decides to leave office. And they'd aim for closer ties with France. Washington himself wouldn't support that, but I think it would still happen.
This would of course cause relations with Britain to be chillier than in OTL, and if the pro-French faction is dominant enough in America, this may cause earlier tension akin to the sort that sparked the War of 1812 in OTL. I think the USA would avoid such a conflict this early on, having barely recovered from its own independence war, but it would be a festering source of resentment between America and Britain. Which I
think would be enough to push America into the French camp if it comes to a new war.
