I am larger than you and rode Mavic Aksiums (24/20 spokes) for 10 years before I got my new bike. Zero issues with them. Only reason I don't any more is I got a new bike with through axles and they won't work on it. A lot of companies don't put rider weight limits on their wheels. Rolf, Bontrager, Spinergy to name a few.
You don't need 32 or 36 hole wheels. I wouldn't go less than 24 in the back, but I probably wouldn't go less than that. Take them to your wheel guy and have him go through them and make sure the spokes are properly tensioned.
My new bike came with DT Swiss 1850 wheels. So far I like them, but I only have 200 miles on them so way too soon to speak about durability. They are tubeless ready and the tires are tubeless ready, but I'm running tubes. I'm planning on switching over to tubeless soon though.
