I'd be saying if you don't do your school work no devise for games/sweets/TV whatever they like the most until they complied.
Some children are easier to bribe than others. Mine are very internally motivated, which is great when they are engaged, interested, have clear goals in mind. They will plug away at something for hours just because they find it fun. It is also great in the teenage years in terms of not giving in to peer pressure. Their Christmas lists are tiny because they don't really want or need much. I was similar and yes it made me a bit geeky, but in my current job it is great as I set my own deadlines, the work is challenging and I find it internally rewarding, but other people might not. I don't feel the need for much in the way of material stuff.
On the other hand they are much harder to bribe than some of their friends. They would just sit for hours doing absolutely nothing in a battle of wills than do something they hate or see as pointless. They just escape into their own little thought processes, but that isn't actually helpful to sit for hours on end doing nothing. I doubt they actually do nothing, they just think, plot, plan, daydream but I can't stop them doing that. For one of them the work is pointless, work that they could do easily two or three years ago, the others are engaged, challenged and happily learning. If we made them do all the schoolwork against their will they would just sit for hours doing nothing, we tried that in the first lockdown. Instead they are fully engaged in educational pursuits all day long, just not school work. Tell them that electronic devices are banned (and we do depending on the 'crime') then they will just say ok and skip away, or stand and argue their point (because they feel that they were right) and then skip away. They have fairly strong moral codes but again it is internalised, they don't say something unpleasant because they don't want to upset the person rather than because they want to avoid punishment. They are not disruptive children in class, they are motivated by teacher praise but that is not as effective when they are not in class. Positive praise works to an extent and we do use that but generally they are just hard to bribe.
I think both extremes of this trait have their benefits and disadvantages. I imagine my children are not unique.
