There are many refrigerators on the market with decent drawers. It just depends on what one has a budget for. Viking for instance make some excellent models and they even have built ins that actually look like cabinets for under the counter with just drawers in them.
Most refrigerator drawers are just made for items like cold cuts, vegetables and salad fixings. There really isn't much weight to those items. It's not like you would stuff a 30lb turkey into a refrigerator drawer.

one drawer for carrots, celery, cukes, radishes
one drawer for peaches, plums, nectarines, citrus
plastic container holds deli meats and pepperoni
another plastic container holds cheeses
a large container with a tight-fitting lid holds the salad mix
top shelf has at least 2 gallon containers of milk, one or two juice bottles, gallon jar of mayo, gallon jar of pepperoncini
leftovers get tossed the next day if not used
just a typical fridge.............

all "extras" in the second fridge
1/2 gallon jar of artichoke hearts
second and third blocks of cheeses
additional heads of lettuce to be "processed" (cleaned and made into salad mix)
etc. etc.

if I am freezing stock or sauces for the freezer, the jars sit in the fridge overnight and then go in the freezers - it's nice to have 2 to play in! and it comes in handy for holidays and big meals -

and it is also an extra fridge/freezer/stove/oven to keep clean as well -

Well, I'll put it this way. If I had to make my own drawers (which it seems I may), then I would build them strong enough to hold more than 30 pounds because if there's anything that needs to be over engineered, its those stupid drawers!

I figure I'm kinda lucky Mama, I have what I call a cold cellar where I am able to store fruit. You can go down there in the summer and smell the apples and pears that were stored there over the winter. Also nice for root veggies.
Plenty of shelves for all my home canned sauces, veggies, fruits and with my pressure canner I have even been canning stocks the past few years. I haven't worked up the nerve to can meat yet though.

I like to use the fridge drawer made for keeping greens somewhat fresher. It has an air flow dial on it. Sealing greens in an air tight container doesn't work very well for me.I have been interested in trying the green bags though but have always figured that they are just another rip off that Ron Popiel or Billy Maze never got their hands on.

Very hard to do .....
