From the list you describe you are actually leaving two categories out:
the allium (garlic, onions, leeks, chives, scallions, shallots ....) and the cruciferous (broccoli, cauliflower, ....)
What you list is the typical vegetables on the FODMAP diet. Monash University here in Australia has a website and even an app to help you understand your way around food www.monashfodmap.com/ibs-central/i-have-ibs/starting-the-low-fodmap-diet/
