Perhaps Camping le Vieux Verger near Nevez, which is an inland village but the site is only 600 metres metres from a pretty stretch of the south coast. As the name says it’s in an old orchard and with fruit trees still there. No reviews on here but quite a few if you search on line.
Camping Les Embruns in Le Pouldu is one of our favourite sites https://www.camping-les-embruns.com/
It's walking distance to the beach and the village is just outside the gates.
Very peaceful and well-kept site.
Shhhhhhhh ditsy! Don’t tell everyone. We have been going there for years and love it!
Another one you could look at is Camping de la Baie in La Trinite sur Mer or Camping de la Plage just next door but if you have a largish outfit, there is more room on La Baie.

How about Camping Les Sables Blancs in Concarneau. Was struck by how quiet it was ... Pool and restaurant overlooking the bay ... Lovely staff ... 200m to a lovely beach ... 20 min walk to the walled town.
We stayed at Camping le Poulquer in Benodet which is pretty quiet ...does have water slides but also has another pool which is more like an upmarket health spa pool ! Also has a small bar, but very civilised. 100yds from the boardwalk and beach and a great location to explore that whole area of Brittany. I just about walked my feet off and it was wonderful !
A quieter suggestion in the area may be Camping les Helles in Sainte Marine on the other side of the Odet estuary ...I wanted to stay there but got out voted ! We did visit the gorgeous beach that it fronts onto, however, and the pretty little harbour at Ste Marine (restaurants, creperies etc) which is five minutes around the coast path. Benodet is a nice 45min walk further over the bridge and along the coast path.
Le Helles is on the quieter side of the Odet river from Benodet, so the benefits of being in a biggish town (there are river taxis) but none of the busy-ness.
When we stayed at Les 2 Fontaines near Nevez (which is a fine site btw but maybe bigger / busier than you want) we went for a walk and found Camping l'Ocean Finistere Sud (not in UKCS) nearby which looked great, very much in the mould of Pors Peron. Great sea views from pitches and a short walk down a country lane to the beach.
