We are fairly hot on learning to do things independently (where it's mainly "things we want them to do" and "things they are near learning to do").
They are 12 and 10, the 12 year old has some SEN. They are now able to go to local shops, including buying the odd household thing (though obviously they prefer to buy sweets, which is OK as long as it's at the weekend!), put their washing on, help to hang it up, empty the dishwasher, DD makes hot drinks but DS doesn't really like them, DD can bake simple cakes independently if given advice, she walks to school and to a local club (the others, and DS school, are too far/inconvenient for independent travel, or the group asks parents to stay), I'm sure there's more.
I listened to this podcast recently - I like the series in general, it's very much our parenting philosophy for our ADHD DS, but this one is with a separate therapist who does what he calls "independence therapy".

What do you, or would you, suggest for independent activities for this age? What would your DC want or what have they asked to do?
One further point is that though both DCs are good in shops and good crossing the road, DS occasionally can't find somewhere he's been before (OK, hands up, I'm occasionally rubbish at that as well!) and he also has no friends (long story, I mean literally zero though). Both ride bikes but when we do roads I'd rather be with them currently (we could of course practice familiar routes before they try them alone).
