Hello, and welcome to the challenging world of feeding ekkies.
I haven't tried any of those, unfortunately, so I can't really say one way or the other.
Some birds are more stubborn than others. The trick here is to be more stubborn than she is. You're right to try and get her off the seeds. They're fatty when given in excess, and can lead to arteriosclerosis. So keep providing as much variety of veggies, grains, and fruits as possible, prepared in as many ways as possible. In the past, for instance, my birds never liked carrots in large pieces or cut up, sliced or diced. But grated? Bring it on! Lol!
A good intro food to try in pomegranate. Rare is the ekkie that wouldn't lose her mind over that fruit! Then try using a cooked base. My favorite for this purpose is Volkmans Fancy Soak & Simmer. Great source of oats, grains and legumes. Quinoa or brown rice works as well. For birds, it's as much about texture as taste. (Their sense of taste is far less sensitive than ours.)
Here's what I usually post up when asked about diet for ekkies:
I tend to provide between 6 and 8 types of food per feeding (2 meals per day), weighted heavily toward the veggie side as only 1 of the food selections in a given meal is a fruit.
Various sprouts, carrots (very important due to the high content of beta carotene - precursor to Vitamin A), bell peppers (red, yellow, orange and green ā also very high in Vitamin A), jalapeno peppers, Jamaican Scotch bonnet peppers, chili peppers, squash (butternut, green and yellow), pumpkin (again, high in Vitamin A), blueberries and pomegranates (both among the most nutritious of fruits), snap peas, broccoli (high in calcium), cactus pears, persimmon, starfruit, bananas, grapes (only for flavor and hydration. Relatively low in nutrition), kale, turnips, radishes, brown rice, quinoa, cucumbers, endives, dandelion (nutritional powerhouse offered at every meal when seasonally available), sweet potato (cooked), red swiss chard, mustard greens, collard greens, kale, cilantro, parsley, watercress, arugula, granny smith apples, papaya (donāt go too heavy on this, as it is a diarrhetic), African horned melon, hominy, oatmeal (sans sugar or flavoring), kiwi, barley, calendula flowers, fennel, chocho beans and garbanzo beans, as well as Volkman's Fancy Soak and Simmer for the majority of their legumes and grains.
For food accents I'll add one or two types of the following as well: star anise, milk thistle, elder berries, rose hips, hibiscus, bee pollen and chamomile flowers.
Twice a month, I'll give some hard-boiled egg (with the crushed shell for calcium). Slightly more frequently during a molt.
For their training treats they get an assortment of unsalted nuts (one to three per bird in a given day, broken into small pieces and fed as rewards during the training sessions). And for their "goodnight treat", up to a teaspoon or two of seeds.
