I did camp quite a lot this summer on the Francés.
Camping on the Camino is a bit different than for example on the American long distance trails like the Appalachian trail. You can't just camp wherever you want, you have to use official campgrounds or camp at albergues.
"Wild camping" is not allowed, and there is no need to be fully self sufficient and/or to carry lots of food and water. Even if you camp, you can go to the cafés/bars/restaurants if you want to, so there's no need for a stove (it is not allowed to be used because of the risk of forest fires, anyway). Many campgrounds do have a restaurant on site. Camping at albergues, you can use the kitchen or join the communal dinner if there is one.
There are some official campgrounds, some of those are more basic (but always with warm showers), some very luxurious with pool and all.
Some albergues will let you camp if you ask nicely and start your question with "If I pay the same as for a bed, is it maybe possible...?".
Price of an official campground is similar to a bed in a private albergue. At some albergues you pay a bit less with a tent, but I always offered the same price, because tent camping is not popular in Spain and it is often assumed that only freeloaders want to camp. Time to work against that prejudice!
Many albergues do not allow camping even if you offer to pay the same price, but will let you sleep outdoors in their garden without a tent. That's a good option in summer in nice weather. Falling asleep under the stars, no snorers...
I camped to avoid bedbugs and covid, then later because of a pet, and also because I just love to sleep in my tent.
Should I walk the Camino again, I'll certainly bring camping gear again.
It is certainly not needed on the Francés, but if you love camping and want to avoid any bed race, busy albergues, and/or bedbugs, it's a nice option.
