As an urban gardener with only a few square meters of balcony space, and also as a bee enthusiast, I am quite fond of annual and perennial herbaceous dicots – they often have a fairly long blooming period, which is good for the insects, and they are more useful for me in terms of growing food because it is possible to get meaningful harvests even with just a few plants, which would not be the case with cereal crops. I make an exception for Alliums (and also – reluctantly – for Muscari, because it blooms at a time when there are few other flowers available for the early spring bees).
My house plants, by contrast, are mostly monocots, though a few eudicots/magnoliids have managed to sneak in (Kalanchoe, Peperomia, Basella, Oxalis).
Given current concerns about pollinator decline, monocots – or at least the grains/grasses – may have a survival advantage, since they are more likely to rely on wind pollination than those dicots that are relevant to humans as food crops.
I looked through the list here https://en.wikipedia.org/wiki/List_of_culinary_fruits
While I am not sure that all the plants on this list are actively grown as crops and eaten as fruit, there do seem to be a few additional monocot candidates, mostly palms:
- acai (Euterpe oleracea)
- jelly palm/pindo date (Butia odorata)
- salak/snake fruit (Salacca zalacca)
- sugar palm (Arenga pinnata)
- hala/screw pine (Pandanus tectorius) (https://www.eattheweeds.com/pandanus/)
- peach palm (Bactris gasipaes) (though this site suggests the fruit is savory and thus more likely to be a culinary vegetable: https://plantpono.org/pono-plants/bactris-gasipaes/)
- buriti (Mauritia flexuosa)
- banana yucca (Yucca baccata) https://www.thespruceeats.com/banana-yucca-aka-yucca-baccata-1337949
- Monstera deliciosa
