Say Napoleon falls sick in the Egyptian campaign and dies.
What would be the goals of another French government? Would they try to conquer more territories or would they be fine with trying to maintain the status quo?
It really depends on who takes over instead of Napoleon.
Maintaining the status quo seems harder to do though than going to war and annexing/puppetizing territories. Europe at the time really didn't look favorably on the Revolution and nobody would love to see a France that was much too strong, except the French.
If Moreau becomes dictator, he would have to rely on some figures, the firts being Talleyrand who favoured a lasting peace and important concessions to do so.
That's assuming Moreau is a good statesman. The problem is that, given his career, that's not a given... The man turned down the offer to lead the Brumaire coup when Napoleon didn't. And he also got involved or caught up in a conspiracy against Napoleon, which led to his exile.
The truth is that we'll never know how good Moreau would have done if he had taken Bonaparte's place. But to assume that he would do as you say is sadly only one of the possibilities of the scenario. Moreau could just also run the country to the ground by making foolish decisions.
Whithout Napoleon's boldness to refuse his counsellors' arguments, it would have been likely for France to search peace and therefore negociate.
The problem is that even if France seeked out peace, the rest of Europe wouldn't necessarilly have been ready to do so.
And even then, the French Revolutionnary mentality wasn't necessarilly aimed at peace. Or at least, not a peace that Europe would necessarilly have tolerated.
That's a common mistake that's made about Napoleon: because of the big role he ended up playing in the events, he tends to be scapegoated into having made the situation worse. He does have his wrongs, but Napoleon's pretty much a product of his time as well. As are a number of Revolutionnary French figure and the various European stateman that Napoleon dealt with and that would still have to deal with the situation if he wasn't in the picture. And a number of the things Napoleon ended up doing just went with the flow of the French Revolution, even if he put his own spin on it.
France would have become a very moderate Republic
Unlikely. At least not without achieving some much needed stability and a period of peace. That's what Napoleon achieved after Brumaire (even if the peace was brief): for all the flaws about the Consulate and Empire, they were fairly moderate compared to the previous revolutionnary governments.
The 1792-1799 years weren't really a model of moderation. And there is no guarantee that Napoelon's replacement would be a moderate.
would make huge territorial concessions (No occupation of the Netherlands, nor North Italy or Switzerland).
Doubtful as well.
For one thing, France was a bit crazy about its natural borders at the time. And depending on where you push the cursor, North Italy and parts of Switzerland can be considered part of that. North Italy for example was once called Cisalpine Gaul, and historically the French always had eyes on Milan, the Savoy domains and Genoa. As for Switzerland, you have the question of the French-speaking cantons or Romandie...
As for the occupation of the rest... People tend to forget that before Napoleon started giving crowns to his relatives and redrawing the map of Europe as he liked... The French Revolution had already done so by creating Sister-republics on its borders. There is no reason to imagine Revolutionnary France would stop doing that.
Diplomatically, the best choice would have to keep the alliance with Spain and get closer to Prussia (playing with the Austro-Prussian rivalry).
There are a number of issues though.
Spain, for one, is a bit of a dodgy and worthless ally to have. Sure it's a major European power but it's in complete decline at the time and with one of the worst royal families ever at the time (Charles IV and Ferdinand VII weren't the brightest bulb in existence). A royal family made of Bourbons to boot, the cousins of the King that the French Revolution beheaded. And that have Britain eyeing their colonial empire...
As for Prussia... The problem is that it was one of the most rabidly opposed state to the Revolution at the time. The Prussians started fighting Fench forces from the start. And for all its rivalry with Austria, the Prussians probably are even less fond of letting France keep the left bank of the Rhine.
