I'd suggest you also widen your search and include Mediums. My daughter is 5’8” 140lbs and the Med fit her pretty well.
Drysuits are more size-flexible than wetsuits. You can wear a slightly-too-large wetsuit and burp out the excess air. Some wrinkles won't hurt.
A too-small wetsuit will stretch and keep you warm. A too-large wetsuit will let in water and make you cold. A too-small drysuit will be restrictive because they don't stretch!
That all said, I have a M Kokatat tropos suit with socks I would consider selling or renting.
