Store size can vary but not so much that it affects product offering, ime. Some states disallow alcohol sales in anything other than liquor stores, others restrict liquor or wine sales but not beer. In those states those TJ's do not sell alcohol, or perhaps beer only.
I buy all dairy (milk, organic or non, eggs, organic or non, butter, organic or non, heavy cream - their organic is great), all cheeses, much produce (I am a huge fan of their Brussels sprouts on the stalk), almond butter, jams, some coffee, evoo, vinegars, breakfast cereals (I like them better and they are much less), breads, dry pastas, basmati and jasmine rices, b/s chicken breasts and other pieces (whole chickens I buy elsewhere - I like chicken <3 lbs), bone-in turkey breast halves, tri-tip, rack of lamb, some lunch meats, canned diced tomatoes and canned beans for hummus), several wines - just to name some of the stuff that are my usual purchases.
