OP - Going down the list though some will be more difficult than others, esp if you have 3 children, with one child (or with lost of help) more realistic.
My DC don't eat junk food, I just don't buy it, I read with them each night, but often let DD and DS1 watch TV while I settle the baby (Only takes 20 mins, but still).
Extra homework, well good luck, hard enough to get DS1 to do the homework from school, he's very strong willed... DD happily did extra reading every night though so depends on the child.
DD has barbies, I didn't buy any of them, all presents from friends for birthdays, same with the disney princess stuff. Not much you can do about that unless you home school them.
They both learn an extra language at school (chose the school because of the excellent language provision), but neither particularly interested in musical instruments and its not something I have prioritised.
We have grown vegetables but TBH can't get either of them to eat them.
None of them have dummies (all three rejected them as babies!), but DS1 (aged 5) and DS2 (aged 1) both have comforters they suck on. Did I plan this - no, was it preferable to them sucking on me in the night - yes! DD sucked her thumb until last year, had to bribe her to stop.
So YANBU to aspire to these things, but I suspect you'll laugh at this list in 5 years time.
