We've only run the bottom delta area (where there are barely any rapids) but this river can be paddled from Lake Nipissing all the way to Georgian Bay. Exploring the delta is amazing on its own. It has massive wide-open sections, and parts just wide enough for a canoe to fit through.
The French is also designated a Canadian Heritage River. It was a key fur trading passage to get from Lake Huron to the Ottawa River with minimal portaging.
Nights
As many as you want. In the delta, mapped below, you can choose any route that you'd like. It can be a loop, a there and back again. Stay a bunch at the same site. Whatever you want it to be, as long as you've booked it ahead of time.
Booking
Since it's a Provincial Park, you'll need to book your sites here. They've recently switched to a book-the-site system like many Ontario parks have moved to. So you won't have the freedom to choose as you go anymore, but at least you'll have some piece of mind that you'll have a site waiting for you when you get there. It's been hard to find sites in the past so this is likely why they switched to this system.
Since a lot of it is accessible by motor boats, the park warden can zip around checking everyone's papers and kicking people off sites if they are over 9 people per site (from personal experience!).
Put-in:
The only put-in that we've ever used is Hartley Bay Marina (Google Maps location). At the desk, they'll hook you up with your site booking printouts and offering parking that's not included in the cost of your park pass.
Route:
While there are many routes that you can take (see suggestions in the map below) we highly recommend the routes that get away from the motor boats which frequent the larger passage ways and are a mixture of park and private cottage land. There are two little tight pathways that flow south from the Pickerel River that are excellent.

Maps by Jeff - French River This is the best map for the French River. You can use the complete map online for planning and the physical maps are made of a very strong polymer so you'll have no need for a map case. Just fold and ram that sucker into your PFD pocket.
French River Map - By Ontario Parks. An older and decent map, but doesn't have as much detail as Jeff's Map linked above. Jeff has added more interesting routes through the small sections where only canoes can go (ok, kayaks). This map is usually available at the Hartley Marina.

Exploring the French River's delta is incredible. There are so many different route options to take, though you do have to book specific sites now, so plan well!
In July of 2018, four families, all with small children (two of which were one-year-olds) paddled the French River for a few nights. Since we all had our hands full with children, we didn't get that far into the park and base-camped. Or at least tried to base-camp until a grumpy park ranger told us on the second day that we had to move since we had too many people on one site. Fair enough. We were definitely over the limit. So we moved to a site that had an adjacent site.
We were enjoying our time on the French river. Swimming, keeping the kids from drowning, paddling around, chasing away a Massasauga Rattler from the site, and eating gloriously.
On the third day we out out for a long day-paddle. We could see smoke coming up from over the tree line to the south. We chatted with some other folks on the river and learned that there's a forest fire south of the park, but it's not coming this way. The smoke was though (and that perhaps should have made us think.) By the end of our day-paddle it was 'snowing' white ash and black smoke had darkened the sun to a red ball (pictures below). The tips of every wave and ripple of the river reflected the dark red. It felt as though we were paddling towards Bowser's lair.
So, we went to bed after watching the red glow on the horizon. The following morning was spent chilling around the campsite. Tim worked on rigging up a sail on a canoe. Others went swimming or just were laying around reading. Things took a bit of a turn when a guy in a small aluminum fishing boat came zipping up to our side hollering, "You've got to evacuate! The fire is coming this way now!"
So, we packed up and started heading back to the marina. Though, we still managed to stop for a swim on the way since it certainly didn't look like the fire was any where close. We also passed by some cottagers on their dock with beers who weren't taking this fire thing very serious.
When we got to the marina we met some people who took it very seriously, in a "run for your lives!" kind of way. Several people ran down the dock and helped us grab the canoes out of the water only removing the large packs. Groups of people hurried the boats to the cars where we started to move with more urgency. The smoke that was settling down all around the area did seem to support the concern.
On our drive out, we were stopped by some fire-fighters at a truck with lights flashing. Using a clipboard, he asked for our names which apparently would be crosschecked with the parks records on who is out on the water. My (Tim) earlier suspicions that this isn't that critical of an emergency were confirmed by the fire-fighter who didn't rush us on but was happy to chit chat about the fire without urgency. Even though the winds had shifted, it was still many hours away from where we were. We definitely needed to evacuate, but our lives were not in any eminent danger.
The wind was blowing quite a bit of smoke across the highway on the way out, which actually became the most concerning part since visibility was reduced. We learned later that the fire never reached all the way to where we camped or the marina. Interestingly enough, it did rip through the area where I wanted to camp, but we didn't get that far in. That section is only accessible by canoe and that fishing boat dude would not have been able to get to us.
Two years later we went back and camped at that burned out site though. It was pretty awesome, but not much shade anymore.
