It's pretty much anything can go these days except honey until after 1yr and whole nuts until 4/5yrs. Unless there's a known allergy in the family.
I preferred to leave leafy things like lettuce until my boys were at least 1 as it can get stuck to the roof of their mouth. Both my boys had family foods from the start, stuff they could pick up and feed themself with. Not hard raw veg though (soft-ish bigger than fist sized where possible). Both have not made huge messes for me to clean up and have been able use cutlery confidently before 18mths. Look up baby led solids/weaning for more info on this if interested. BB does have a thread on this (currently on phone so hard to link for you)
