As to the crotch strap, use what you like, I like a one inch for my warm water rigs.Interesting. I really disliked the 1" strap that came with my DSS harness and have no problems with the 2" on my current Piranha harness.
I'm not a fan of weight belts. I use cheap XS Scuba trim pockets on my waist belt for lead. I use steel backplates and dive warm water so only need 2 or 3 pounds per pocket and am comfortable with just a velcro flap. I can pull the weights out manually if I need to dump them. I'll stick weight on the cam band(s) on the rare occasions I've needed more weight because I've added a vest or other exposure gear.
I do not use a weight belt for my warm water and travel BP/wings. I used to use the XS QR pouches and still do but have become somewhat disenchanted with them because they seem to fall apart after a long season. So, recently, I converted my VDH wing and plate to these as a trial run to see if they hold up better:
But they cost a bit more, could buy a couple of sets of the XS QR pouches for one set of the Dive Rites which are made in America and that matters to me.
XS QR pouches:
XS Scuba Quick-Release Single Weight Pocket
Do you teach diving, do you find the need for additional weight on certain dives, or is your trim in the water not exactly as you want it? All these needs can be met with XS Scuba's Quick-Release Singl

In warm water in a 3mm suit I typically use 2 pounds in each waist pocket and two pounds in each of two cam band pockets (non QR). For my heavy suit for cooler water I still can use a weight belt, typically splitting the weight between my belt, cam band pouches and the stainless Freedom Plate helps as well. I have tried larger weight pockets on my waist straps but being only 30 inches around my middle parts I run out of room and the pockets come together before the buckle pulls up snug. Still working on that. I can eat all of the left over Halloween candy or maybe try some different pouches. Not sure the best direction to go on that.
