Yah greg has solid advice, call your local freediving shop and see if they will let you try a suit on if you are buying from them. Otherwise its a crapshoot on fit. I'm 5'11 165lbs. I wear off the rack L on jbl and bodyglove. A Medium on spetton and seac. A XL on Yazbek. And a flipping XXL on immersion. The euro suits are often cut a lot smaller and it really depends on the maker. Custom suits are a lot more expensive but youll get a guranteed fit.
As for thickness it depends on how cold you get and how much natural insulation you have
. I'm sure age plays a part too because I'm cold all the freaking time, I wear a 5mm when it's above 64 degrees, otherwise its 7mm below that. Even then I'll get cold after two hours underwater. Each manufacturer may use a diff grade of neoprene (yamamoto, sheico etc) and the sofer more supple ones tear easier and also compress faster so there's always a give n take.
If you are shore diving, I always go with ones with reinforced knee and elbow pads and of course a chest loading pad. Farmer Johns are typically warmer than high waist pants, but are harder to take off when you have to take a dump.
