Hey Merel, of course be prepared with some good bug spray. I would also spend the money on a bug shirt. I'm an "Original Bug Shirt" fan. The bugs are horrendous here in the central interior, we live in ours and love them!
Not trying to freak you out about the bugs but I think if you're not used to it, it could put a damper on your trip. Better to be over prepared than under. That being said, the bugs at Clearwater, Azure, or Murtle aren't that bad.
Clearwater/Azure has outfitters with boat rentals as well as a water taxi service in case you are short on time. You also have a short river to portage up and paddle down for a little fun. I think these lakes would be exactly what you're looking for.
Murtle would be just as fitting, just harder with the portage in.
We have a trip report from Clearwater/Azure under the BC Trip Reports section.
The further South you go, the less bugs there are.
Unfortunately, the further South you go, the more people you get.
Hope you have a great time! Paddle safe.
