If it were me, I would either pass D, E, and F, individually through ChipMixer or a coinjoin before consolidating them at a later date, or keep them separate altogether and just use them for various payments as you suggest.
An alternative for really small inputs: you can convert them to Bitcoin on the Lightning Network by using one of the custodial wallets. I've used BlueWallet and Phoenix for this (research the wallets yourself before funding them, so you know potential pitfalls), and if you create different wallets, you'll get different funding addresses. Don't do all inputs at once, and you'll break most blockchain links.
The wallet company will know the link between addresses though.
