We find cheerios to be a good one (careful they do have added sugar/salt, etc. so not the BEST), pears cut up without the skin so long as they are fairly soft, bananas cut up, avocado cut up (the slimy things do better when coated with something to make it easier to grip, like a breadcrumb almost LOL), french toast, scrambled eggs, small pastas like pastina, etc.
(Some of these are from way back when DD was a baby as DS has more intolerances and food issues and can't have them all yet, so it's hard to remember what she could eat and when, but I know she was VERY good with finger foods by 12 months as at her bday party she was walking around with raw broccoli and chomping away on it LOL)
