What if you drop the idea of compliance in the first place? I found it makes everything a lot less of a battle. And no, I don't mean going full on permissive and just letting them do whatever they want. I just mean that I don't expect to be able to fully control the actions of another person, though I do accept that I have more life experience and foresight than young children and as the responsible adult, it is my place to make sure they are safe, get enough food/sleep/movement/not too much screen time etc and and learn what reasonable social behaviour is, which includes not clonking your annoying sibling on the head with a wooden train bridge (it's happened). I just think you can do this without a general expectation of compliance as a goal in itself.
I find that it just changes the way you look at things. So if you don't have the expectation in the first place to be able to make them do something, you have to use other things instead. One shift is that while it's very difficult to make anyone do something they don't want to do, it is often much easier to prevent something you don't want happening, especially when children are small because they don't have that much power - you're in control of a lot including their environment, for example. Then the other is that rather than "making" them do things you're looking at how to set things up for success so that the thing you want them to do is attractive or easy or natural for them, or seeing it as something they are learning (and will get wrong in the process, and might need coaching/support/structured practice to get better at it) and seeing frustrating behaviour as more information/communication about a problem to be solved or skill to be practised, rather than just an act of defiance which needs to be stamped out. Problem solving is the sort of "final boss" skill - trying to see what they need/want, what I need/want, is it important, is there a win win solution which works for all of us? This comes in more when they are older but you can start using bits of it when they are little.
So I might control the environment (e.g. put things I don't want them to have out of reach) or act as a physical barrier between them and the thing e.g. close the door of the room, place myself between arguing siblings, or herd them away while talking about some interesting thing in a different part of the house, or even just change the scenery e.g. by taking them outside. Interrupting behaviour can stop it in the moment (though won't necessarily prevent it happening in the future).
If they can't handle a certain amount of freedom then I might not give it e.g. unsupervised access to certain rooms. There is a great concept in RIE called a "yes space" which is essentially having at least one area of your house that is childproofed to the extent that you're not having to tell them "no" about anything. Access to siblings often scuppers this - the group I used to be in tended to suggest separate spaces for siblings for that reason. I never went this far TBH but my DC definitely get into states where they need separate spaces to play or exist without encroaching on each other, because they have just gone past their capacity of being able to engage nicely.
But TBH the overall picture of DC that age being repeatedly destructive IME means they are bored or need more structured/targeted input. And if you're on summer holidays it can be a really sudden adjustment when they've been at school/nursery for at least half days if this stops and you have to juggle child wrangling plus household chores all at once, and they're reeling either because they are exhausted from a full year of school or they have been used to the highly stimulating, structured activity of nursery and then suddenly they're at home with just their older sibling to bother.
At those ages they are basically a full time job so there isn't much space for in-depth cleaning jobs as well - you can work up to it but not if they aren't used to that norm yet, and especially less so if they are antsy because of the above. I would not really expect to be able to clean a room completely unimpeded by two children of this age, it's something I'd only do if another adult was there or at least one was sleeping or perhaps they were pacified with TV. I might be able to do something like stick some chemical cleaners around in the kitchen/bathroom and then close the door to that room as they do their thing, coming back in 30/60 mins to rinse them off quickly and maybe do a cursory scrub. Or open a room, stick the robot hoover in and close the door. Or change a bed, one item at a time knowing I might be interrupted and/or the items might end up on the floor or used for a pillow fight in between. I know you didn't want that to be used as an example, but I could give other examples if preferred.
I'm not saying this BTW to say that I do this perfectly at all times or that it is easy or simple, but it is something of a mindset shift which has helped me, and is completely workable IME, or at least no less functional than any other parenting approach!
